I like FF way better than IE, don't get me wrong. But even some forms don't function right since I upgraded to 1.5.

I can't use the quick reply form here at BP or anywhere else. Have to go to the advanced reply.
Opera IS a good browser, and really fast. But the speed, I believe, comes from the fact that it doesn't have all the functions FF or IE has. Opera isn't very compatible with certan web features and codes, etc.
