      8 * Bug 1895990 - figshare login broken with dFPI enabled
      9 *
     10 * The websites that use figshare for login require unpartitioned third-party
     11 * cookie access for https://figshare.com. The figshare login process sets a
     12 * third-party cookie for https://figshare.com, which is used as an proof of
     13 * authentication on redirect back to the main site. This shim adds a request
     14 * for storage access for https://figshare.com when the user tries to log in.
