Mozilla’s latest Firefox nightly build disconnected Backspace button to return to the previous page. The browser developers made this decision to prevent accidental data loss.

The Backspace key will be disabled by default in Firefox 86, but you can get it back by following these steps:

In the address bar, enter about:config;
Change the parameter browser.backspace_action to .

Firefox release manager Pascal Chevreul suggested using a keyboard shortcut instead of Backspace Alt + Left arrow for Windows or Command + Left arrow for macOS.

Company representatives created Seven years ago, track record on the Bugzilla site to discuss the need to disable the Backspace key after the problem of data loss from completed forms.

Google disabled the ability to go back to the Backspace button in its Chrome browser in 2014. Microsoft made the same decision for the Edge browser.

For a long time Firefox and Internet Explorer 11 were the only browsers to support the Backspace key.
