1 Defect Severity 2 =============== 3 4 Definition 5 ---------- 6 7 We use the ``severity`` field in Bugzilla to indicate the scope of a 8 bug's effect on Firefox. 9 10 The field is display alongside the bug's priority. 11 12 Values 13 ------ 14 15 Severity levels and their definitions are enumerated at https://wiki.mozilla.org/BMO/UserGuide/BugFields#bug_severity. 16 17 By default, new bugs have a severity of ``--``. 18 19 Examples of S1 bugs 20 ^^^^^^^^^^^^^^^^^^^ 21 22 - WebExtensions disabled for all users 23 - Web search not working from URL bar 24 - Crashes with data loss 25 26 Examples of S2 bugs 27 ^^^^^^^^^^^^^^^^^^^ 28 29 Bugs that could reasonably be expected to cause a Firefox user to switch browsers, 30 either because the severity is bad enough, or the frequency of occurrence is high enough. 31 32 - `Bug 1640441 <https://bugzilla.mozilla.org/show_bug.cgi?id=1640441>`__ - Slack hangs 33 indefinitely in a onResize loop 34 - `Bug 1645651 <https://bugzilla.mozilla.org/show_bug.cgi?id=1645651>`__ - Changes in 35 Reddit's comment section JS code makes selecting text slow on Nightly 36 37 Bugs involving contractual partners (if not an S1) 38 39 Bugs reported from QA 40 41 - `Bug 1640913 <https://bugzilla.mozilla.org/show_bug.cgi?id=1640913>`__ - because an 42 important message is not visible with the dark theme. It's not marked as S1 since the 43 issue is reproducible only on one OS and the functionality is not affected. 44 - `Bug 1641521 <https://bugzilla.mozilla.org/show_bug.cgi?id=1641521>`__ - because videos 45 are not working on several sites with ETP on (default). This is not an S1 since turning 46 ETP off fixes the issue. 47 48 Fuzzblocker bugs, which prevent fuzzing from making progress 49 50 Examples of S3 bugs 51 ^^^^^^^^^^^^^^^^^^^ 52 53 Bugs filed by contributors as part of daily refactoring and maintenance of the code base. 54 55 `Bug 1634171 <https://bugzilla.mozilla.org/show_bug.cgi?id=1634171>`__ - Visual artifacts around circular images 56 57 Bugs reported from QA 58 59 - `Bug 1635105 <https://bugzilla.mozilla.org/show_bug.cgi?id=1635105>`__ because 60 the associated steps to reproduce are uncommon, 61 and the issue is no longer reproducible after refresh. 62 - `Bug 1636063 <https://bugzilla.mozilla.org/show_bug.cgi?id=1636063>`__ since it's 63 reproducible only on a specific web app, and only with a particular set of configurations. 64 65 66 Rules of thumb 67 -------------- 68 69 - The severity of most bugs of type ``task`` and ``enhancement`` will be 70 ``N/A`` 71 - **Do not** assign bugs of type ``defect`` the severity ``N/A``
