I'm... kind of tempted to actually use IE9

Go ahead and try it. You'll know within a week if you care about the difference.

I use IE9, and it works fine.

IE9 is pretty good. My main problem is just the way it renders text, which looks weird (I don't know if there's a setting I missed or something). I just like how light and responsive Chrome feels. Plus, I don't really care about using extensions anymore, making Firefox seem pointless (though I think the newest version is pretty sharp).

I use Firefox for it's profile sync feature, user interface extensibility (especially mouse gestures) and Win/Mac/Linux cross platform compatibility. I am aware that Chrome has these things and is faster (and doesn't lock up for 20-30 seconds on first boot in Windows), but I don't trust Google with my password data and UI extensions in Firefox just work better and can do more.

IE and Safari don't have these features, so I don't use them.

OP, what kind of monster are you?

He'll come back. They always come back.
