If there’s one thing that drives me crazy about using multiple operating systems, it’s the inconsistency in keyboard shortcuts… when you hit the backspace key in Firefox on Windows it normally goes back to the previous page, but it doesn’t on Ubuntu Linux.
Luckily this is a very simple tweak, and you don’t even have to reboot Firefox.
Type about:config into the address bar, and then filter by the following key:
Double-click on the item in the list and change the value to 0.
The change should be immediate – you can hit the backspace key to go right back to whatever you were doing (probably reading this)
This tip should work on any platform… I’m not sure if all versions of Linux have the same annoyance, but at least Ubuntu does.
