Hello,

Is there a way to restore backspace button function in the newest version of Firefox, so when pressing it the previous page opened? This function was very helpful for me!

Hi,

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 also use the recommended Alt + Left arrow (Command + Left arrow on Mac) shortcut instead.
