Firefox Beta

February 23, 2021

Version 87.0beta, first offered to Beta channel users on February 23, 2021

Firefox Beta gets updated several times per week and as a consequence, the release notes for the Beta channel are updated continuously to reflect features that have reached sufficient maturity to benefit from community feedback and bug reports. In addition to these release notes, you can follow ongoing development on our @FirefoxBeta Twitter account.


  • “Find in page” can now display marks next to the scrollbar corresponding to the positions of matches.


  • To prevent user data loss when filling out forms, the Backspace key as a navigation shortcut for "Go back one page" is now disabled. To re-enable the Backspace keyboard shortcut, you can change the about:config preference browser.backspace_action to 0. You can also use the recommended Alt + Left arrow (Command + Left arrow on Mac) shortcut instead.

  • We've removed some items from the Library button that weren't used often, or have other access points in the browser.

  • We've simplified the Help menu by reducing some redundant items, or items that point to support pages that can also be accessed via the Get Help item.

  • We've greatly simplified the Web Developer menu.
