I downloaded and installed Firefox 3 Beta 3 and it’s a pretty solid beta so far. No crashes or anything and it’s bloody fast. Probably as fast if not faster than Safari. I’m impressed. Very impressed. I only wished some of my add-ons would work with it. The interface is revamped for OS X and looks like it’s part of the OS now. If you want to experiment, you can download Firefox 3 Beta 3 for Linux, Mac, or Windows here.
