85.0 Firefox Release

January 26, 2021

Version 85.0, first offered to Release channel users on January 26, 2021

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

At Mozilla, we believe you have a right to privacy. You shouldn’t be tracked online. Whether you are checking your bank balance, looking for the best doctor, or shopping for shoes, unscrupulous tracking companies should not be able to track you as you browse the Web. For that reason, we are continuously working to harden Firefox against online tracking of our users.

New

  • Firefox now protects you from supercookies, a type of tracker that can stay hidden in your browser and track you online, even after you clear cookies. By isolating supercookies, Firefox prevents them from tracking your web browsing from one site to the next.

  • It’s easier than ever to save and access your bookmarks. Firefox now remembers your preferred location for saved bookmarks, displays the bookmarks toolbar by default on new tabs, and gives you easy access to all of your bookmarks via a toolbar folder.

  • The password manager now allows you to remove all of your saved logins with one click, as opposed to having to delete each login individually.
