While entering data in a form, I sometimes hit the backspace key and it goes to the previous internet page and I lose the data. How do I disable this key?

The backpage is usually while using a drop down window. Data from the entire page is lost, because it's not on an autosave.

Hello olmstedhomested,

Thank you for contacting Mozilla Support. With these instructions you can either remap the backspace to another function or turn it off altogether.

  1. Type about:config in the address bar and press Enter.
  2. Press the big button to bypass the warning.
  3. In the search box, paste browser.backspace_action
  4. In the search results, double-click browser.backspace_action and set its value to 1 or 2.
  • Value 1 Pressing [Backspace] will scroll up a page in the current document and [Shift]+[Backspace] will scroll down.
  • Value 2 will simply unmap the backspace key.

I hope this solves your issue.

Cheers, Patrick
