Firefox is by far the best browser available. What makes it great is the wide variety of extensions. If you are working on a web design or development project be sure to checkout Firebug - its a real time saver!
The only complaint that I have about Firefox is that it isn't very "Mac like" when using OS X. I've heard that this is supposed to change in the upcoming version 3 so I'm still giving it a full 5 star rating.
