I use att yahoo. it runs pretty fast and it opens up your e-mail whenever you get on. Plus it provides news, sports other stuff too. The toolbar lets you go pretty much anywhere on yahoo. Home, games, protection, news, help, yellow pages, finance, music, sports, personals, shopping, and geocities. Those things I read right off of my toolbar!
IE kept on freezing my computer though. =( So, I used firefox. Firefox is pretty good. I used it for quite a long time. I wanted to try something else. I picked Google Chrome. Overall, I like Google Chrome the most. It's really fast. So.. 1.Google Chrome 2.Firefox 3.IE
I haven't tried Opera yet. I'll probably try it soon. =P
