Firefox has some downsides...

- Show frame in right click doesn't unfold sometimes... (yeah it's active!)
- If you go back -1 in history, the page won't go back to the position where you left it, but it loads at the top!...
- GIANT tabs and ctrl+t is to be used for new tabs... opera uses ctrl+n for now tabs... I like opera's way (maybe shortkeys can be changed in firefox... didn't check)

+Thunderbird mailclient rocks!
