Here's my two cents. I HATE Explorer. It seems like every worm, virus, and trojan out there targets Explorer. With that being said, I still have it b/c there are some sites that will only allow you to use explorer (drives me nuts). I LOVE Firefox, but sometimes it crashes if I have too much stuff going on at one time. I think that's b/c of my PC and not Firefox. I haven't tried chrome yet, so I have no opinion about that one. I hope this answers your question.
