Disabilitare l'uscita da Firefox senza richiesta di conferma CTRL-Q
Firefox 10
Firefox 3
For Firefox 3, you can download & install it, it’s called Keyconfig (Mozilla Addons) KeyConfig (OLD).
By the way if you didn’t get Firefox 3 yet you have no excuse do it now!, it’s really the best web browser around! How to use the plug-in?
Just install it, restart Firefox then go to Tools > Keyconfig, or use shortcut Ctrl+Shift+F12 a box will pop-up with the list of keyboard shortcuts, modify or deactivate the ones you want, I could have just changed the shortcut for tab close, but I really never use it, I just disabled.
