Mozilla released Firefox 81 Stable to the public on September 22, 2020. The new versions of the Firefox web browser are available via automatic updates and also as direct downloads.

Now 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 default, dark and light themes, with this release, Firefox 81 introduces the Alpenglow theme. A colorful appearance for buttons, menus, and windows.

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.

Now Firefox supports something called 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.

Other changes in Firefox 81

  • Now Picture-in-Picture is 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.
  • Firefox 81 expanded supported file types – .xml, .svg, and .webp – so files you’ve downloaded can be opened right in Firefox.

Various bug fixes and new policies have been implemented. You can see more details in the release notes.
