annoyance from the first second Rated 1 out of 5 stars

I couldn't open it because default keybinding F12 was already in use by another app. There is no configuration-option outside Firebug so I had to change the keybinding for the app that already had F12 as shortcut-key. After this I could open Firebug but when I tried to give Firebug a new keybinding, it refused to accept a keybinding that was already in use by other apps. Isn't that crazy ? So I had to change again the keybinding for the app that used F12 because I gave it my only free function key that was left. Finally Firebug accepted SOME new keybindings.
So inconsequent and annoying that I immediately dislike Firebug.
