81.0

New

  • You can pause and play audio or video in Firefox right from your keyboard or headset, giving you easy access to control your media when in another Firefox tab, another program, or even when your computer is locked.
  • In addition to our default, dark and light themes, with this release, Firefox introduces the Alpenglow theme: a colorful appearance for buttons, menus, and windows. You can update your Firefox themes under settings or preferences.
  • For our users in the US and Canada, Firefox can now save, manage, and auto-fill credit card information for you, making shopping on Firefox ever more convenient.
    To ensure the smoothest experience, this will be rolling out to users gradually.
  • Firefox supports AcroForm, which will soon allow you to fill in, print, and save supported PDF forms and the PDF viewer also has a new fresh look.
  • Our users in Austria, Belgium and Switzerland using the German version of Firefox will now see Pocket recommendations in their new tab featuring some of the best stories on the web.
    If you don’t see them, you can turn on Pocket articles in your new tab by following these steps.
    In addition to Firefox’s new tab, Pocket is also available as an app on iOS and Android.

Fixed

  • Various security fixes.
  • We’ve fixed a bug for users of language packs where the default language was reset to English after Firefox updates.
  • Browser native HTML5 audio/video controls received several important accessibility fixes:
  • Audio/video controls remain accessible to screen readers even when they are temporarily hidden visually.
  • Audio/video elapsed and total time are now accessible to screen readers where they weren't previously.
  • Various unlabelled controls are now labelled making them identifiable to screen readers.
  • Screen readers no longer intrusively report progress information unless the user requests it.

Changed:

  • You will soon find Picture-in-Picture more easily on all the videos you watch with new iconography.
  • The bookmarks toolbar is now automatically revealed once bookmarks are imported into Firefox, making it easier to find your most important websites.

Developer

  • TypeScript files are now properly identified in the Debugger panel and labeled with corresponding icons making it easier for you to find these files in the list.
  • HTTP JSON responses using XSSI prevention characters are properly parsed and JSON data presented in a form of an expandable tree.
    This allows easy inspection of such HTTP responses through traditional (expandable) tree UI.
  • It’s possible to pause on script first statement, which is useful e.g. in cases where developers want to debug side effects caused by script execution or timers.
  • The color vision deficiency simulation in the accessibility panel of Developer Tools is now more accurate.
    We removed protanomaly, deuteranomaly and tritanomaly and added achromatopsia.

    Users of Firefox 68 ESR will be automatically upgraded to the Firefox 78 ESR series with the release of 78.3.

Developer

  • We’ve shipped an experimental sidebar panel in the inspector to Firefox Developer Edition that helps developers more quickly identify potential browser compatibility problems based on MDN data.
  • In the Network Monitor request list, a turtle icon is shown for "slow" requests that exceed a threshold for the waiting time.

    Users required to use a primary password will only be asked to create a primary password the first time they try to save a password.

Developer

    The async execution chains are shown in the Debugger’s call stack, but also for stack traces in Console errors and Network initiators.
  • Erroneous network responses with 4xx/5xx status codes display as errors in the Console, making it easy to understand them in the context of related logs.
