Right now, I'm using opera. Opera is not very user friendly, but once you get used to this, it's very handy!
My brother uses Mozilla Firefox, which has more add-ons and more user friendly. The remaining Internet Exploler is reserved for my dad, but he don't care about other browser. So there is total 3 browser in one computer. Which one of these three you think is the best? Or what are you using right now?
