I would consider IceCat, but it looks like development has fallen behind Firefox considerably.

I mean no offense by this but I consider myself a privacy wonk and that website is a bit too tin foil hat even for me.

I think we're in a bad way as far as choices go for browsers these days, but Firefox seems like the best of a bad situation to me. If people are still concerned, they should take a look at the changes made to Firefox for the Tor browser.
