Anyway… there were one thing that was making me crazy. Firefox 3 didn’t use Backspace key as a shortcut to the Back function, i.e., pressing backspace didn’t make you return to the previous web page. This is something I use A LOT on Windows on any browser, so not having this possibility is a major turn of. I don’t even know why the hell Mozilla don’t turn this option as default since this is like something taken for granted, at least for me.
Anyway… the good news is it’s a very simple thing to fix.
With Firefox open (duh!):
1. In your Address Bar type: about:config (at this point Firefox will ask you if you want to continue… you do!).
2. Use the Filter Bar and type backspace
3. Now double click the result of the filtering (confirm if it is what you see in the above picture) and change the value to 0 (zero).
Tada! It should be working now… Ok. Back to Surfing!
