Firefox Release

April 5, 2022

Version 99.0, first offered to Release channel users on April 5, 2022


  • You can now toggle Narrate in ReaderMode with the keyboard shortcut "n."

  • You can find added support for search—with or without diacritics—in the PDF viewer.

  • The Linux sandbox has been strengthened: processes exposed to web content no longer have access to the X Window system (X11).

  • Firefox now supports credit card autofill and capture in Germany and France.




  • Gallery mode in the Zoom web client is now accessible in Firefox 99. Display of video is not always working with breakout rooms in gallery mode.

    • When a user of the Zoom web client enters a breakout room, one's self view and of other participants may not appear. Leaving the breakout room and re-entering it should resolve the issue.
