Keep backspacing out of your Guide Console?

In Firefox, the backspace button is a shortcut key to returning to the previously viewed webpage (same as pushing the "back" key on your toolbar).

If you're like me, you've pushed the backspace button too many times accidentally. Its frustrating especially when you're in the middle of the question, you've realized you accidentally "backspaced out" of your question screen, and sometimes may even realize you have lost your question!

Well you can disable that feature.

Type "about:config" in your Firefox url address bar
Click "I'll be careful, I promise" on the warning screen
Search for browser.backspace_action and double click
Change the value to "2"
