INTERNET EXPLOR- oh who am i kidding.
I used to have a really nice dark clean theme in Firefox but that's the only good thing I can say about it... I've always felt that Firefox was less stable- at least Chrome doesn't freeze when trying to watch a YouTube video...
Or maybe that's just because of the shit laptop I had back then.
I still use Chrome because (I think this is an advantage anyways) it beats Firefox with it's separate process for each tab. This might be different for computers that aren't so fast, but with my old laptop Chrome was still faster than Firefox.
The only reason why I had both browsers installed was because my retarded online math textbook didn't work on Chrome
