This is a funny thread.
Being a coder at heart I use FF2. The extensions , which you can also write yourself, are very very useful.
IE belongs to Microsoft so I wouldn't touch it with yours cuz you don't know what standards they decide to impose on you or tie you into. Opera is based on IE code and I found Opera cluttered and clunky.
As to the mentioned problems at the begining of this thread I've never had them so it must be a User Error or an ID10T error.
