So I just dl'd Firefox 2 Beta 2, and I must say:
I LOVE IT!
It improves on many of Firefox 1.5's great features, like plug-ins and extensions, but it also gained some new features. It now feels a lot like Opera; Little [x] 's on the tabs, sleeker design... and other stuff. Another cool thing is a built in spell checker! If you misspell something, it underlines it in red. Then you right click the word, and it gives you spelling suggestions! Now none of you n00bz (<- it didn't underline that?!? ) have an excuse to misspell! Even now, 10 min after download, I am discovering new things.
