Firefox Release

October 20, 2020

Version 82.0, first offered to Release channel users on October 20, 2020

We'd like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox.


  • With this release, Firefox introduces a number of improvements that make watching videos more delightful:

    • the Picture-In-Picture button has a new look and position, making it easier for you to find and use the feature.
    • Picture-In-Picture now has a keyboard shortcut for Mac users (Option + Command + Shift + Right bracket) that works before you start playing the video.
    • For Windows users, Firefox now uses DirectComposition for hardware decoded video, which will improve CPU and GPU usage during video playback, improving battery life.
  • Firefox is faster than ever with improved performance on both page loads and start up time:

    • Websites that use flexbox-based layouts load 20% faster than before;
    • Restoring a session is 17% quicker, meaning you can more quickly pick up where you left off;
    • For Windows users, opening new windows got quicker by 10%.
  • You can now explore new articles when you save a webpage to Pocket from the Firefox toolbar.

  • WebRender continues to roll out to more Firefox users on Windows.


  • Screen reader features which report paragraphs now correctly report paragraphs in Firefox instead of lines.

  • Various security fixes


  • Credit card auto-fill is now more accessible with the card type, and the card number in the card editor now available to screen readers.

  • Printing dialog errors for invalid form entries are now reported to screen readers.


  • Developer Information
  • MediaSession API has been enabled by default which allows web authors to provide custom behaviors for standard media playback interactions, giving them more options than ever.

  • DevTools now shows server sent events in the Network panel. This allows a server to send new data to a web page at any time allowing developers to see events they previously couldn't and help with lower-level troubleshooting.
