Just downloaded Firefox 4

I use Chrome for my gmail. Otherwise, I use Firefox. I have no clue if its 3 or 4 though.

FF4 works just fine for me, starts faster and loads faster for me. I've got nothing negative to say about it other than they moved the refresh button and made it harder for me to spam it with a simple click.
