In Firefox 87 some menus have been reorganized and some items were removed and others rearranged.

See the "Changed" section in the Firefox 87.0 and 88.0 Release notes.


  • To prevent user data loss when filling out forms, we’ve disabled the Backspace key as a navigation shortcut for the back navigation button. To re-enable the Backspace keyboard shortcut, you can change the about:config preference browser.backspace_action to 0.

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".

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