Nouveautés de Firefox 82.0 (20/10/2020)


  • 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.

    • 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%.

  • 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.
