Change log

All notable changes to this program are documented in this file.

0.36.0 (2025-02-25, `a3d508507022`)

Known problems

• Startup hang with Firefox running in a container (e.g. snap, flatpak):

When Firefox is packaged inside a container (like the default Firefox browser shipped with Ubuntu 22.04), it may see a different filesystem to the host. This can affect access to the generated profile directory, which may result in a hang when starting Firefox. Workarounds are listed in the geckodriver [usage documentation].

• Virtual Authenticator endpoints are currently unreliable.

Since their introduction in geckodriver 0.34.0, several Virtual Authenticator endpoints have been reported as non-functional or behaving unexpectedly. We recommend avoiding the use of these commands until the known issues have been resolved.

Added

• Support for searching the Firefox Developer Edition’s default path on macOS.

Implemented by [Gatlin Newhouse].

• Ability to push a WebExtension archive as created from a base64 encoded string

to an Android device.

• Added an allowPrivateBrowsing field for POST /session/{session id}/moz/addon/install

to allow the installation of a WebExtension that is enabled in Private Browsing mode.

• Introduced the [--allow-system-access] command line argument for geckodriver, which will

be required for future versions of Firefox (potentially starting with 138.0) to allow testing in the chrome context.

• Added support for preserving crash dumps for crash report analysis when

Firefox crashes. If the MINIDUMP_SAVE_PATH environment variable is set to an existing folder, crash dumps will be saved accordingly. For mobile devices, the generated minidump files will be automatically transferred to the host machine.

For more details see the documentation of how to handle [crash reports].

Changed

• Updated the type of the x and y fields of pointer move actions (mouse and touch)

from integer to fractional numbers to ensure a more precise input control.

Note: Support for fractional values is available starting with Firefox 137. For older versions, clients or tests must explicitly pass integer values for both fields.

• Replaced serde_yaml with yaml-rust because it's no longer officially supported.

• The --enable-crash-reporter command line argument has been deprecated to

prevent crash reports from being submitted to Socorro. This argument will be completely removed in the next version.

Instead, use the MINIDUMP_SAVE_PATH environment variable to get minidump files saved to a specified location.

Fixed

• Fixed route registration for WebAuthn commands, which were introduced in

geckodriver 0.34.0 but mistakenly registered under /sessions/ instead of /session/, causing them to be non-functional.

Removed

• Removed the -no-remote command-line argument usage for Firefox, which does no longer exist.

0.35.0 (2024-08-06, `9f0a0036bea4`)

Known problems

• Startup hang with Firefox running in a container (e.g. snap, flatpak):

When Firefox is packaged inside a container (like the default Firefox browser shipped with Ubuntu 22.04), it may see a different filesystem to the host. This can affect access to the generated profile directory, which may result in a hang when starting Firefox. Workarounds are listed in the geckodriver [usage documentation].

• Virtual Authenticator endpoints are currently unreliable.

Since their introduction in geckodriver 0.34.0, several Virtual Authenticator endpoints have been reported as non-functional or behaving unexpectedly. We recommend avoiding the use of these commands until the known issues have been resolved.

Added

• Support for [Permissions] that allow controlling permission prompts

within the browser. This enables automated tests to handle scenarios involving permissions like geolocation, notifications, and more.

• The command line flag --enable-crash-reporter has been added, to allow

the crash reporter in Firefox to automatically submit crash reports to Mozilla's crash reporting system if a tab or the browser itself crashes.

Note that this feature is disabled by default and should only be used when a crash situation needs to be investigated. See our documentation for [crash reports] in how to share these with us.

Implemented by [Razvan Cojocaru].

Changed

• The validation of the unhandledPromptBehavior capability has been enhanced

to support finer configuration options for the [User Prompt Handler] which are particularly used by [WebDriver BiDi].

Fixed

• The [Switch To Frame] command now correctly raises an "invalid argument"

error when the id parameter is missing.

Implemented by [James Hendry].

Removed

• Removed support for session negotiation using the deprecated

desiredCapabilities and requiredCapabilities.

Implemented by [James Hendry].

• Removed support for the moz:useNonSpecCompliantPointerOrigin capability,

which has not been supported since Firefox 116.

0.34.0 (2024-01-03, `c44f0d09630a`)

Known problems

• Startup hang with Firefox running in a container (e.g. snap, flatpak):

When Firefox is packaged inside a container (like the default Firefox browser shipped with Ubuntu 22.04), it may see a different filesystem to the host. This can affect access to the generated profile directory, which may result in a hang when starting Firefox. Workarounds are listed in the geckodriver [usage documentation].

• Virtual Authenticator endpoints are currently unreliable.

Since their introduction in geckodriver 0.34.0, several Virtual Authenticator endpoints have been reported as non-functional or behaving unexpectedly. We recommend avoiding the use of these commands until the known issues have been resolved.

Added

• Support for [Virtual Authenticators]

[Virtual Authenticators] serve as a WebDriver Extension designed to simulate user authentication (WebAuthn) on web applications during automated testing. This functionality encompasses a range of methods, including passwords, biometrics, and security keys.

Geckodriver supports all available commands:

- [Add Virtual Authenticator] - [Remove Virtual Authenticator] - [Add Credential] - [Get Credentials] - [Remove Credential] - [Remove All Credentials] - [Set User Verified]

• Support for using a page range as integer for the [Print] command.

Implemented by [Mitesh Gulecha].

Changed

• The error handling has undergone refactoring, now utilizing the

anyhow and thiserror crates.

Implemented by [James Hendry].

• Specifying --port=0 as an argument allows geckodriver to dynamically find

and use an available free port on the system.

• Updated dependencies (base64, clap, rust-url)

Fixed

• While searching for a default Firefox installation on the system, geckodriver

used the Contents/MacOS/firefox-bin executable instead of the binary specified in the app bundle's info.plist file. This behavior resulted in a malfunction due to a regression in Firefox, particularly affecting the Firefox 121 release.

• The Firefox version check has been extended to enable the execution of

distributions with custom prefixes for the application name.

Implemented by [Razvan Cojocaru].

Removed

• Removed the unknown path error which is not part of the WebDriver specification.

Implemented by [James Hendry].

0.33.0 (2023-04-03, `a80e5fd61076`)

Known problems

• Startup hang with Firefox running in a container (e.g. snap, flatpak):

When Firefox is packaged inside a container (like the default Firefox browser shipped with Ubuntu 22.04), it may see a different filesystem to the host. This can affect access to the generated profile directory, which may result in a hang when starting Firefox. Workarounds are listed in the geckodriver [usage documentation].

• Potential hang with `moz:debuggerAddress` capability set to `true`:

After enabling the site-isolation feature in Firefox with geckodriver 0.32.1 some WebDriver clients like Selenium that use the Chrome DevTools Protocol (CDP) by default for logging events could trigger a hang in Firefox's experimental CDP implementation. The fix for this problem will be shipped with Firefox 112. Until then the following Firefox preferences should be set:

- fission.bfcacheInParent: false - fission.webContentIsolationStrategy: 0

Added

• Support for [Get Computed Label] and [Get Computed Role]

The command [Get Computed Label] returns the accessibility label (sometimes also referred to as Accessible Name), which is a short string that labels the function of the control (e.g. the string "Comment" or "Sign In" on a button).

The command [Get Computed Role] returns the reserved token value (in ARIA, button, heading, etc.) that describes the type of control or content in the element.

Note that the minimum required Firefox version is 113.0.

• Support for [Find Element From Shadow Root] and [Find Elements From Shadow Root]

The commands allow a lookup of individual elements or collections of elements within an open or closed Shadow DOM. All location strategies except Tag name and XPath selector are currently supported.

Note that the minimum required Firefox version is 113.0.

Changed

• The Mozilla specific capability moz:useNonSpecCompliantPointerOrigin has been

marked as deprecated. Its removal is planned for the Firefox 116.0 release.

0.32.2 (2023-02-08, `602aa16c20d4`)

Known problems

• Startup hang with Firefox running in a container (e.g. snap, flatpak):

When Firefox is packaged inside a container (like the default Firefox browser shipped with Ubuntu 22.04), it may see a different filesystem to the host. This can affect access to the generated profile directory, which may result in a hang when starting Firefox. Workarounds are listed in the geckodriver [usage documentation].

• Potential hang with `moz:debuggerAddress` capability set to `true`:

After enabling the site-isolation feature in Firefox with geckodriver 0.32.1 some WebDriver clients like Selenium that use the Chrome DevTools Protocol (CDP) by default for logging events could trigger a hang in Firefox's experimental CDP implementation. The fix for this problem will be shipped with Firefox 112. Until then the following Firefox preferences should be set:

- fission.bfcacheInParent: false - fission.webContentIsolationStrategy: 0

Fixed

• With the release of geckodriver 0.32.1 the marionette crate was inappropriately

bumped to a semver incompatible version and caused cargo install geckodriver to fail for older releases.

0.32.1 (2023-02-02, `b7f075124503`)

Known problems

• Startup hang with Firefox running in a container (e.g. snap, flatpak):

When Firefox is packaged inside a container (like the default Firefox browser shipped with Ubuntu 22.04), it may see a different filesystem to the host. This can affect access to the generated profile directory, which may result in a hang when starting Firefox. Workarounds are listed in the geckodriver [usage documentation].

• Potential hang with `moz:debuggerAddress` capability set to `true`:

After enabling the site-isolation feature in Firefox with geckodriver 0.32.1 some WebDriver clients like Selenium that use the Chrome DevTools Protocol (CDP) by default for logging events could trigger a hang in Firefox's experimental CDP implementation. The fix for this problem will be shipped with Firefox 112. Until then the following Firefox preferences should be set:

- fission.bfcacheInParent: false - fission.webContentIsolationStrategy: 0

Fixed

• When using the boolean capability moz:debuggerAddress with a value of true

the site-isolation feature in Firefox will no longer accidentally be turned off. This behavior affected all users of WebDriver clients especially Selenium, which set this capability by default, and caused Firefox on desktop systems to be launched in an unsupported mode.

0.32.0 (2022-10-13, `4563dd583110`)

Added

• Native aarch64 builds of geckodriver for Linux and Windows are now available.

• Support wheel input source for [Actions], which is associated with a

wheel-type input device. This endpoint is supported by geckodriver when using Firefox version ≥106.

• Support touch as pointerType for pointer input source for [Actions],

which is associated with a touch input device. This also includes the addition of all the remaining properties for pointer input sources as specified by WebDriver. This endpoint is supported by geckodriver when using Firefox version ≥104.

Fixed

• Using geckodriver to launch Firefox inside a sandbox -- for example

a Firefox distribution using Snap or Flatpak -- can fail with a "Profile not found" error if the sandbox restricts Firefox's ability to access the system temporary directory. geckodriver uses the temporary directory to store Firefox profiles created during the run.

This issue can now be worked around by using the --profile-root command line option or setting the TMPDIR environment variable to a location that both Firefox and geckodriver have read/write access to e.g.:

`bash % mkdir $HOME/tmp % geckodriver --profile-root=~/tmp `

or

`bash % TMPDIR=$HOME/tmp geckodriver `

Alternatively, geckodriver may be used with a Firefox install that is not packaged inside a sandbox e.g. from [mozilla.org].

• The sandboxed Firefox binary is now automatically detected when geckodriver

is used from within a Snap confinement.

Implemented by [Olivier Tilloy].

• On MacOS the geckodriver binary is now technically both signed and notarized.

Note: The actual validation can only be performed if the machine that starts the geckodriver binary for the very first time is online. You can find more details on how to work around this issue in the [macOS notarization] section of the documentation.

• The backup of the original Firefox preferences are now correctly restored

on Android when the WebDriver session ends.

Changed

• Update dependencies

0.31.0 (2022-04-11, `b617178ef491`)

Known problems

• Firefox running in Linux Sandbox (e.g. Snap package):

Using geckodriver to launch Firefox inside a sandbox -- for example a Firefox distribution using Snap or Flatpak -- can fail with a "Profile not found" error if the sandbox restricts Firefox's ability to access the system temporary directory. geckodriver uses the temporary directory to store Firefox profiles created during the run.

As workaround geckodriver may be used with a Firefox install that is not packaged inside a sandbox e.g. from [mozilla.org].

• macOS 10.15 (Catalina) and later:

Due to the requirement from Apple that all programs must be notarized, geckodriver will not work on Catalina if you manually download it through another notarized program, such as Firefox.

Whilst we are working on a repackaging fix for this problem, you can find more details on how to work around this issue in the [macOS notarization] section of the documentation.

Added

• Users with the [Rust] toolchain installed can now build and install

geckodriver from [crates.io] using Cargo:

% cargo install geckodriver

• Support for [Get Element Shadow Root]

Implemented by [David Burns].

The standardised WebDriver [Get Element Shadow Root] endpoint provides a way to retrieve the Shadow Root of a given web element. This endpoint is supported by geckodriver when using Firefox version ≥96.

• Support for additional hosts and origins

Users can now specify a list of allowed Host and Origin headers for incoming requests using the [--allow-hosts] and [--allow-origins] command line options, respectively. When such a flag is provided, exactly the given values will be permitted.

By default any request with an Origin header is rejected, and only requests containing the bound hostname (specified via --host), or an IP address, in the Host header are allowed. These configuration options are designed to support scenarios where geckodriver is running on a different network node to the host e.g. some container based setups.

Fixed

• Geckodriver lets Marionette itself select a system allocated port, so that

it's no longer required to specify a fixed port when using a custom Firefox profile. This is done by reading the MarionetteActivePort file of the Firefox profile in-use. This helps to avoid port collisions when multiple Firefox instances are run in parallel.

• It's no longer possible to specify both the androidPackage and binary

capabilities togther within [moz:firefoxOptions] because these capabilites are mutually exclusive.

0.30.0 (2021-09-16, `d372710b98a6`)

Security Fixes

• CVE-2021-4138

Fixed a DNS rebinding issues by enforcing a stricter Host header check.

Reported by Gabriel Corona.

- Improved Host header checks to reject requests not sent to a well-known local hostname or IP, or the server-specified hostname.

Known problems

• geckodriver restricts connections to local IP addresses. This can interfere

with deployments in which geckodriver is running on a different network node to the tests e.g. some container or virtual-machine based setups.

• macOS 10.15 (Catalina) and later:

Due to the requirement from Apple that all programs must be notarized, geckodriver will not work on Catalina if you manually download it through another notarized program, such as Firefox.

Whilst we are working on a repackaging fix for this problem, you can find more details on how to work around this issue in the [macOS notarization] section of the documentation.

• Android:

For releases of Firefox 89.0 and earlier Marionette will only be enabled in GeckoView based applications when the Firefox preference devtools.debugger.remote-enabled is set to true via [moz:firefoxOptions].

Added

• Support for WebDriver clients to opt in to [WebDriver BiDi].

Introduced the new boolean capability [webSocketUrl] that can be used by WebDriver clients to opt in to a bidirectional connection. A string capability with the same name will be returned by [NewSession], which contains the WebSocket URL of the newly created WebDriver session in the form of: ws://host:port/session/<session id>.

When running on Android a port forward will be set on the host machine, which is using the exact same port as on the device.

All the supported WebDriver BiDi commands depend on the version of Firefox, and not geckodriver. The first commands will be shipped in Firefox 94.

• It's now possible to set additional preferences when a custom profile has been

specified. At the end of the session they will be removed.

Fixed

• Added validation that the --host argument resolves to a local IP address.

• Limit the --foreground argument of Firefox to MacOS only.

• Increased Marionette handshake timeout to not fail for slow connections.

• Marionette:Quit is no longer sent twice during session deletion.

• When deleting a session that was attached to an already running browser

instance, the browser is not getting closed anymore.

• Android

- Starting Firefox on Android from a Windows based host will now succeed as we are using the correct Unix path separator to construct on-device paths.

- Arguments as specified in [moz:firefoxOptions] are now used when starting Firefox.

- Port forwards set for Marionette and the WebSocket server ([WebDriver BiDi]) are now correctly removed when geckodriver exits.

- The test root folder is now removed when geckodriver exists.

0.29.1 (2021-04-09, `970ef713fe58`)

Known problems

• macOS 10.15 (Catalina) and later:

Due to the requirement from Apple that all programs must be notarized, geckodriver will not work on Catalina if you manually download it through another notarized program, such as Firefox.

Whilst we are working on a repackaging fix for this problem, you can find more details on how to work around this issue in the [macOS notarization] section of the documentation.

• Android:

Marionette will only be enabled in GeckoView based applications when the Firefox preference devtools.debugger.remote-enabled is set to true via [moz:firefoxOptions]. This will be fixed in the Firefox 90 release for Android.

Added

• When testing GeckoView based applications on Android it's now enough to

specify the androidPackage capability. The appropriate activity name, and required intent arguments will now automatically be used for applications released by Mozilla.

• Native AArch64 (M1) builds of geckodriver for MacOS are now available. These

are currently shipped as Tier2 due to missing test infrastructure. Please let us know if you experience issues.

Fixed

• Fixed a stack overflow crash in thread 'webdriver dispatcher' when

handling certain device errors.

• Fixed an application crash due to missing permissions on unrooted devices

by changing the location of the test related files, e.g the profile folder. Therefore the deprecated &#x2D;&#x2D;android-storage command line argument now defaults to the sdcard option, which changed its location to $EXTERNAL_STORAGE/Android/data/%androidPackage%/files/. With this change proper support for unrooted devices running Android 10+ has been added.

Note: Do not use the &#x2D;&#x2D;android-storage command line argument anymore unless there is a strong reason. It will be removed in a future release.

0.29.0 (2021-01-14, `cf6956a5ec8e`)

Known problems

• macOS 10.15 (Catalina) and later:

Due to the requirement from Apple that all programs must be notarized, geckodriver will not work on Catalina if you manually download it through another notarized program, such as Firefox.

Whilst we are working on a repackaging fix for this problem, you can find more details on how to work around this issue in the [macOS notarization] section of the documentation.

• Android:

Marionette will only be enabled in GeckoView based applications when the Firefox preference devtools.debugger.remote-enabled is set to true via [moz:firefoxOptions]. This will be fixed in one of the upcoming Firefox for Android releases.

In some cases geckodriver could crash due to a stack overflow when handling certain device errors.

On unrooted Android 10+ devices startup crashes of the application can be experienced due to an inappropriate location of test related files, e.g the profile folder.

Added

• Introduced the new boolean capability [moz:debuggerAddress] that can be used

to opt-in to the experimental Chrome DevTools Protocol (CDP) implementation. A string capability with the same name will be returned by [NewSession], which contains the host:port combination of the HTTP server that can be used to query for websockets of available targets.

Note: For this experimental feature the site-isolation support of Firefox aka [Fission] will be not available.

0.28.0 (2020-11-03, `c00d2b6acd3f`)

Known problems

• macOS 10.15 (Catalina) and later:

Due to the requirement from Apple that all programs must be notarized, geckodriver will not work on Catalina if you manually download it through another notarized program, such as Firefox.

Whilst we are working on a repackaging fix for this problem, you can find more details on how to work around this issue in the [macOS notarization] section of the documentation.

• Android:

Marionette will only be enabled in GeckoView based applications when the Firefox preference devtools.debugger.remote-enabled is set to true via [moz:firefoxOptions]. This will be fixed in one of the upcoming Firefox for Android releases.

In some cases geckodriver could crash due to a stack overflow when handling certain device errors.

On unrooted Android 10+ devices startup crashes of the application can be experienced due to an inappropriate location of test related files, e.g the profile folder.

Added

• The command line flag --android-storage has been added, to allow geckodriver

to also control Firefox on root-less Android devices. See the [documentation][Flags] for available values.

Fixed

• Firefox can be started again via a shell script that is located outside of the

Firefox directory on Linux.

• If Firefox cannot be started by geckodriver the real underlying error message is

now being reported.

• Version numbers for minor and extended support releases of Firefox are now parsed correctly.

Removed

• Since Firefox 72 extension commands for finding an element’s anonymous children

and querying its attributes are no longer needed, and have been removed.

0.27.0 (2020-07-27, `7b8c4f32cdde`)

Security Fixes

• CVE-2020-15660

Improved validation of incoming requests to prevent remote requests being treated as local.

Reported by Gabriel Corona.

- Added additional checks on the Content-Type header for POST requests to disallow application/x-www-form-urlencoded, multipart/form-data and text/plain.

- Added checking of the Origin header for POST requests.

- The version number of Firefox is now checked when establishing a session.

Known problems

• macOS 10.15 (Catalina) and later:

Due to the requirement from Apple that all programs must be notarized, geckodriver will not work on Catalina if you manually download it through another notarized program, such as Firefox.

Whilst we are working on a repackaging fix for this problem, you can find more details on how to work around this issue in the [macOS notarization] section of the documentation.

• Android:

Marionette will only be enabled in GeckoView based applications when the Firefox preference devtools.debugger.remote-enabled is set to true via [moz:firefoxOptions]. This will be fixed in one of the upcoming Firefox for Android releases.

In some cases geckodriver could crash due to a stack overflow when handling certain device errors.

Added

• To set environment variables for the launched Firefox for Android,

it is now possible to add an env object on [moz:firefoxOptions] (note: this is not supported for Firefox Desktop)

• Support for print-to-PDF

The newly standardised WebDriver [Print] endpoint provides a way to render pages to a paginated PDF representation. This endpoint is supported by geckodriver when using Firefox version ≥78.

• Support for same-site cookies

Cookies can now be set with a same-site parameter, and the value of that parameter will be returned when cookies are retrieved. Requires Firefox version ≥79. Thanks to [Peter Major] for the patch.

Fixed

• Android:

- Firefox running on Android devices can now be controlled from a Windows host.

- Setups with multiple connected Android devices are now supported.

- Improved cleanup of configuration files. This prevents crashes if the application is started manually after launching it through geckodriver.

• Windows and Linux binaries are again statically linked.

0.26.0 (2019-10-12, `e9783a644016'`)

Note that with this release the minimum recommended Firefox version has changed to Firefox ≥60.

Known problems

• macOS 10.15 (Catalina) and later:

Due to the recent requirement from Apple that all programs must be notarized, geckodriver will not work on Catalina if you manually download it through another notarized program, such as Firefox.

Whilst we are working on a repackaging fix for this problem, you can find more details on how to work around this issue in the [macOS notarization] section of the documentation.

• Windows:

You must still have the [Microsoft Visual Studio redistributable runtime] installed on your system for the binary to run. This is a known bug which we weren't able fix for this release.

• Android:

Marionette will only be enabled in GeckoView based applications when the Firefox preference devtools.debugger.remote-enabled is set to true via [moz:firefoxOptions]. This will be fixed in one of the upcoming Firefox for Android releases.

In some cases geckodriver could crash due to a stack overflow when handling certain device errors.

Added

• Support for Firefox on Android

Starting with this release geckodriver is able to connect to Firefox on Android systems, and to control packages based on [GeckoView].

Support for Android works by the geckodriver process running on a host system and Firefox running within either an emulator or on a physical device connected to the host system. This requires you to first [enable remote debugging on the Android device].

The WebDriver client must set the [platformName capability] to "android" and the androidPackage capability within [moz:firefoxOptions] to the Android package name of the Firefox application.

The full list of new capabilities specific to Android, instructions how to use them, and examples can be found in the [moz:firefoxOptions] documentation on MDN.

When the session is created, the platformName capability will return "android" instead of reporting the platform of the host system.

Changed

• Continued Marionette refactoring changes

0.25.0 came with a series of internal changes for how geckodriver communicates with Firefox over the Marionette protocol. This release contains the second half of the refactoring work.

Fixed

• Connection attempts to Firefox made more reliable

geckodriver now waits for the Marionette handshake before assuming the session has been established. This should improve reliability in creating new WebDriver sessions.

• Corrected error codes used during session creation

When a new session was being configured with invalid input data, the error codes returned was not always consistent. Attempting to start a session with a malformed capabilities configuration will now return the [invalid argument] error consistently.

0.25.0 (2019-09-09, `bdb64cf16b68`)

Note to Windows users! With this release you must have the [Microsoft Visual Studio redistributable runtime] installed on your system for the binary to run. This is a known bug with this particular release that we intend to release a fix for soon.

Added

• Added support for HTTP HEAD requests to the HTTPD

geckodriver now responds correctly to HTTP HEAD requests, which can be used for probing whether it supports a particular API.

Thanks to [Bastien Orivel] for this patch.

• Added support for searching for Nightly’s default path on macOS

If the location of the Firefox binary is not given, geckodriver will from now also look for the location of Firefox Nightly in the default locations. The ordered list of search paths on macOS is as follows:

1. /Applications/Firefox.app/Contents/MacOS/firefox-bin 2. $HOME/Applications/Firefox.app/Contents/MacOS/firefox-bin 3. /Applications/Firefox Nightly.app/Contents/MacOS/firefox-bin 4. $HOME/Applications/Firefox Nightly.app/Contents/MacOS/firefox-bin

Thanks to [Kriti Singh] for this patch.

• Support for application bundle paths on macOS

It is now possible to pass an application bundle path, such as /Applications/Firefox.app as argument to the binary field in [moz:firefoxOptions]. This will be automatically resolved to the absolute path of the binary when Firefox is started.

Thanks to [Nupur Baghel] for this patch.

• macOS and Windows builds are signed

With this release of geckodriver, executables for macOS and Windows are signed using the same certificate key as Firefox. This should help in cases where geckodriver previously got misidentified as a virus by antivirus software.

Removed

• Dropped support for legacy Selenium web element references

The legacy way of serialising web elements, using {"ELEMENT": <UUID>}, has been removed in this release. This may break older Selenium clients and clients which are otherwise not compatible with the WebDriver standard.

Thanks to [Shivam Singhal] for this patch.

• Removed --webdriver-port command-line option

--webdriver-port <PORT> was an undocumented alias for --port, initially used for backwards compatibility with clients prior to Selenium 3.0.0.

Changed

• Refactored Marionette serialisation

Much of geckodriver’s internal plumbing for serialising WebDriver requests to Marionette messages has been refactored to decrease the amount of manual lifting.

This work should have no visible side-effects for users.

Thanks to [Nupur Baghel] for working on this throughout her Outreachy internship at Mozilla.

• Improved error messages for incorrect command-line usage

Fixed

• Errors related to incorrect command-line usage no longer hidden

By mistake, earlier versions of geckodriver failed to print incorrect flag use. With this release problems are again written to stderr.

• Search system path for Firefox binary on BSDs

geckodriver would previously only search the system path for the firefox binary on Linux. Now it supports different BSD flavours as well.

0.24.0 (2019-01-28, `917474f3473e`)

Added

• Introduces strictFileInteractability capability

The new capability indicates if strict interactability checks should be applied to <input type=file> elements. As strict interactability checks are off by default, there is a change in behaviour when using [Element Send Keys] with hidden file upload controls.

• Added new endpoint GET /session/{session id}/moz/screenshot/full

for taking full document screenshots, thanks to Greg Fraley.

• Added new --marionette-host <hostname> flag for binding to a

particular interface/IP layer on the system.

• Added new endpoint POST /session/{session_id}/window/new

for the [New Window] command to create a new top-level browsing context, which can be either a window or a tab. The first version of Firefox supporting this command is Firefox 66.0.

• When using the preference devtools.console.stdout.content set to

true logging of console API calls like info(), warn(), and error() can be routed to stdout.

• geckodriver now sets the app.update.disabledForTesting preference

to prevent Firefox >= 65 from automatically updating whilst under automation.

Removed

• ARMv7 HF builds have been discontinued

We announced back in September 2018 that we would stop building for ARM, but builds can be self-serviced by building from source.

To cross-compile from another host system, you can use this command:

% cargo build --target armv7-unknown-linux-gnueabihf

Changed

• Allow file uploads to hidden <input type=file> elements

Through a series of changes to the WebDriver specification, geckodriver is now aligned with chromedriver’s behaviour that allows interaction with hidden <input type=file> elements.

This allows WebDriver to be used with various popular web frameworks that—through indirection—hides the file upload control and invokes it through other means.

• Allow use of an indefinite script timeout for the [Set Timeouts]

command, thanks to reimu.

Fixed

• Corrected Content-Type of response header to utf-8 to fix

an HTTP/1.1 compatibility bug.

• Relaxed the deserialization of timeouts parameters to allow unknown

fields for the [Set Timeouts] command.

• Fixed a regression in the [Take Element Screenshot] to not screenshot

the viewport, but the requested element.

0.23.0 (2018-10-03)

This release contains a number of fixes for regressions introduced in 0.22.0, where we shipped a significant refactoring to the way geckodriver internally dealt with JSON serialisation.

Removed

• The POST /session/{session id}/element/{element id}/tap endpoint

was removed, thanks to Kerem Kat.

Changed

• [webdriver crate] upgraded to 0.38.0.

Fixed

• desiredCapabilities and requiredCapabilities are again

recognised on session creation

A regression in 0.22.0 caused geckodriver to recognise desired and required instead of the correct desiredCapabilities and requiredCapabilities. This will have caused significant problems for users who relied on this legacy Selenium-style session creation pattern.

Do however note that support for Selenium-styled new session requests is temporary and that this will be removed sometime before the 1.0 release.

• duration field made optional on pause actions

A regression in 0.22.0 caused the pause action primitive to require a duration field. This has now been fixed so that pauses in action chains can be achieved with the default duration.

• Log level formatted to expected Marionette input

A regression in 0.22.0 caused the log level to be improperly formatted when using Firefox pre-releases. This is now fixed so that the requested log level is correctly interpreted by Marionette.

• temporary field on addon installation made optional

A regression in 0.22.0 caused the temporary field for POST /session/{session id}/moz/addon/install to be mandatory. This has now been fixed so that an addon is installed permanently by default.

• SHA1s in version information uses limited number of characters

The SHA1 used in --version when building geckodriver from a git repository is now limited to 12 characters, as it is when building from an hg checkout. This ensures reproducible builds.

0.22.0 (2018-09-15)

This release marks an important milestone on the path towards a stable release of geckodriver. Large portions of geckodriver and the [webdriver] library it is based on has been refactored to accommodate using [serde] for JSON serialization.

We have also made great strides to improving [WebDriver conformance], to the extent that geckodriver is now almost entirely conforming to the standard.

Added

• Support for WebDriver web element-, web frame-, and web window

identifiers from Firefox.

• Added support for the non-configurable setWindowRect capability

from WebDriver.

This capability informs whether the attached browser supports manipulating the window dimensions and position.

• A new extension capability moz:geckodriverVersion is returned

upon session creation.

Changed

• All JSON serialization and deserialisation has moved from

rustc_serialize to [serde].

• The HTTP status codes used for [script timeout] and [timeout]

errors has changed from Request Timeout (408) to Internal Server Error (500) in order to not break HTTP/1.1 Keep-Alive support, as HTTP clients interpret the old status code to mean they should duplicate the request.

• The HTTP/1.1 Keep-Alive timeout for persistent connections has

been increased to 90 seconds.

• An [invalid session ID] error is now returned when there is no

active session.

• An [invalid argument] error is now returned when [Add Cookie]

is given invalid parameters.

• The handshake when geckodriver connects to Marionette has been

hardened by killing the Firefox process if it fails.

• The handshake read timeout has been reduced to 10 seconds instead

of waiting forever.

• The HTTP server geckodriver uses, [hyper], has been upgraded to

version 0.12, thanks to [Bastien Orivel].

• geckodriver version number is no longer logged on startup, as

the log level is not configured until a session is created.

The version number is available through --version, and now also through a new moz:geckodriverVersion field in the matched capabilities.

• [webdriver crate] upgraded to 0.37.0.

Fixed

• Parsing [timeout object] values has been made WebDriver conforming,

by allowing floats as input.

• Implicit downloads of OpenH264 and Widevine plugins has been disabled.

• The commit hash and date displayed when invoking --version

is now well-formatted when built from an hg repository, thanks to [Jeremy Lempereur].

• Many documentation improvements, now published on

<https://firefox-source-docs.mozilla.org/testing/geckodriver/>.

0.21.0 (2018-06-15)

Note that with this release of geckodriver the minimum recommended Firefox and Selenium versions have changed:

• Firefox 57 (and greater)
• Selenium 3.11 (and greater)

Added

• Support for the chrome element identifier from Firefox.

• The unhandledPromptBehavior capability now accepts `accept and

notify, dismiss and notify, and ignore` options.

Note that the unhandled prompt handler is not fully supported in Firefox at the time of writing.

Changed

• Firefox will now be started with the -foreground and -no-remote

flags if they have not already been specified by the user in [moz:firefoxOptions].

-foreground will ensure the application window gets focus when Firefox is started, and -no-remote will prevent remote commands to this instance of Firefox and also ensure we always start a new instance.

• WebDriver commands that do not have a return value now correctly

return {value: null} instead of an empty dictionary.

• The HTTP server now accepts Keep-Alive connections.

• Firefox remote protocol command mappings updated.

All Marionette commands changed to make use of the WebDriver: prefixes introduced with Firefox 56.

• Overhaul of Firefox preferences.

Already deprecated preferences in Firefox versions earlier than 57 got removed.

• [webdriver crate] upgraded to 0.36.0.

Fixed

• Force use of IPv4 network stack.

On certain system configurations, where localhost resolves to an IPv6 address, geckodriver would attempt to connect to Firefox on the wrong IP stack, causing the connection attempt to time out after 60 seconds. We now ensure that geckodriver uses IPv4 consistently to both connect to Firefox and for allocating a free port.

• geckodriver failed to locate the correct Firefox binary if it was

found under a firefox or firefox-bin directory, depending on the system, because it thought the parent directory was the executable.

• On Unix systems (macOS, Linux), geckodriver falsely reported

non-executable files as valid binaries.

• When stdout and stderr is redirected by geckodriver, a bug prevented

the redirections from taking effect.

0.20.1 (2018-04-06)

Fixed

• Avoid attempting to kill Firefox process that has stopped.

With the change to allow Firefox enough time to shut down in 0.20.0, geckodriver started unconditionally killing the process to reap its exit status. This caused geckodriver to inaccurately report a successful Firefox shutdown as a failure.

The regression should not have caused any functional problems, but the termination cause and the exit status are now reported correctly.

0.20.0 (2018-03-08)

Added

• New --jsdebugger flag to open the [Browser Toolbox] when Firefox

launches. This is useful for debugging Marionette internals.

• Introduced the temporary, boolean capability

moz:useNonSpecCompliantPointerOrigin to disable the WebDriver conforming behavior of calculating the Pointer Origin.

Changed

• HTTP status code for the [StaleElementReference] error changed

from 400 (Bad Request) to 404 (Not Found).

• Backtraces from geckodriver no longer substitute for missing

Marionette stacktraces.

• [webdriver crate] upgraded to 0.35.0.

Fixed

• The Firefox process is now given ample time to shut down, allowing

enough time for the Firefox shutdown hang monitor to kick in.

Firefox has an integrated background monitor that observes long-running threads during shutdown. These threads will be killed after 63 seconds in the event of a hang. To allow Firefox to shut down these threads on its own, geckodriver has to wait that time and some additional seconds.

• Grapheme clusters are now accepted as input for keyboard input

to actions.

Input to the value field of the keyDown and keyUp action primitives used to only accept single characters, which means geckodriver would error when a valid grapheme cluster was sent in, for example with the tamil nadu character U+0BA8 U+0BBF.

Thanks to Greg Fraley for fixing this bug.

• Improved error messages for malformed capability values.

0.19.1 (2017-10-30)

Changed

• Search suggestions in the location bar turned off as not to

trigger network connections

• Block addons incompatible with E10s

Fixed

• Marionette stacktraces are now correctly propagated

• Some error messages have been clarified

Removed

• Removed obsolete socksUsername and socksPassword proxy

configuration keys because neither were picked up or recognised

0.19.0 (2017-09-16)

Note that with geckodriver 0.19.0 the following versions are recommended:

• Firefox 55.0 (and greater)
• Selenium 3.5 (and greater)

Added

• Added endpoint:

- POST /session/{session id}/window/minimize for the [Minimize Window] command

• Added preference extensions.shield-recipe-client.api_url to disable

shield studies which could unexpectedly change the behavior of Firefox

object creation in content processes

Changed

• Log all used application arguments and not only -marionette

• Early abort connection attempts to Marionette if the Firefox process

closed unexpectetly

• Removed deprecated socksProxyVersion in favor of socksVersion

• Removed ftpProxyPort, httpProxyPort, sslProxyPort, and

socksProxyPort because ports have to be set for ftpProxy, httpProxy, sslProxy, and socksProxy using ":<PORT>"

• The proxyType noproxy has been replaced with direct in accordance

with recent WebDriver specification changes

• The [WindowRectParameters] have been updated to return signed 32-bit

integers in accordance with the CSS and WebDriver specifications, and to be more liberal with the input types

• Mapped the [FullscreenWindow] to the correct Marionette command

• To make sure no browser process is left behind when the [NewSession]

fails, the process is closed immediately now

• /moz/addon/install command accepts an addon parameter, in lieu of

path, containing an addon as a Base64 string (fixed by [Jason Juang])

• [webdriver crate] upgraded to version 0.31.0

• [mozrunner crate] upgraded to version 0.5.0

Removed

• Removed the following obsolete preferences for Firefox:

- browser.safebrowsing.enabled - browser.safebrowsing.forbiddenURIs.enabled - marionette.defaultPrefs.port - marionette.logging

command, which makes geckodriver compatible with Firefox 56 and greater

• Linux x86 (i686-unknown-linux-musl) builds are fixed

0.17.0 (2017-06-09)

Added

• Added endpoints:

Changed

• Increasing the length of the network.http.phishy-userpass-length

preference will cause Firefox to not prompt when navigating to a website with a username or password in the URL

• Library dependencies upgraded to mozrunner 0.4 and mozprofile 0.3

to allow overriding of preferences via capabilities if those have been already set in the profile

• Library dependencies upgraded to mozversion 0.1.2 to only use the

normalized path of the Firefox binary for version checks but not to actually start the browser, which broke several components in Firefox on Windows

Fixed

• The [SetWindowRect] command now returns the [WindowRectResponse]

when it is done

• Use ASCII versions of array symbols to properly display them in the

Windows command prompt

• Use [SessionNotCreated] error instead of [UnknownError] if there

is no current session

0.16.1 (2017-04-26)

Fixed

• Read Firefox version number from stdout when failing

to look for the application .ini file (fixes [Selenium #3884](https://github.com/SeleniumHQ/selenium/issues/3884))

• Session is now ended when closing the last Firefox window (fixes

#613)

0.16.0 (2017-04-21)

Note that geckodriver v0.16.0 is only compatible with Selenium 3.4 and greater.

Added

• Support for WebDriver-conforming [New Session] negotiation, with

desiredCapabilities/requiredCapabilities negotiation as fallback

• Added two new endpoints:

- GET /session/{session id}/window/rect for [Get Window Rect] - POST /session/{session id}/window/rect for [Set Window Rect]

• Align errors with the [WebDriver errors]:

- Introduces new errors [ElementClickIntercepted], [ElementNotInteractable], [InvalidCoordinates], [NoSuchCookie], [UnableToCaptureScreen], and [UnknownCommand] - Removes ElementNotVisible and InvalidElementCoordinates errors

Removed

• Removed following list of unused endpoints:

• Preferences passed in a profile now take precedence over

set of default preferences defined by geckodriver (fixed by Marc Fisher) - The exceptions are the marionette.port and marionette.log.level preferences and their fallbacks, which are set unconditionally and cannot be overridden

• Pointer move action’s element key changed to origin, which

lets pointer actions originate within the context of the viewport, the pointer’s current position, or from an element

• Now uses about:blank as the new tab document; this was previously

disabled due to bug 1333736 in Marionette

children and querying its attributes; accessible through the /session/{sessionId}/moz/xbl/{elementId}/anonymous_children to return all anonymous children and /session/{sessionId}/moz/xbl/{elementId}/anonymous_by_attribute to return an anonymous element by a name and attribute query

• Introduced a [moz:firefoxOptions] capability to customise a Firefox

session:

- The binary, args, and profile entries on this dictionary is equivalent to the old firefox_binary, firefox_args, and firefox_profile capabilities, which have now all been removed

- The log capability takes a dictionary such as {log: "trace"} to enable trace level verbosity in Gecko

- The prefs capability lets you define Firefox preferences through capabilities

• Re-introduced the --webdriver-port argument as a hidden alias to

--port

Changed

• firefox_binary, firefox_args, and firefox_profile capabilities

removed in favour of the [moz:firefoxOptions] dictionary detailed above and in the [README]
