I'm not surprised because I use Firefox mostly for Myspace and other websites that it doesn't work 100 percent with Safari 3.0 beta so I hope they will work out most of the bugs, though. Safari 3.0 is clearly MUCH faster than Firefox.
Firefox isn't the best browser in the world, but it's nice. I might be going to use Safari the most when they work out most of the bugs in the final version.
