I used to use Firefox a lot, I found it very strong in its performance. It can open tens of web pages at a time which is very useful to me. The bad point is that it doesn't support as many Plug-ins as IE does, this means we can't fullfil some function thru Firefox like e-Pay etc. Any last I am using IE, and find that it can also open tens of web pages at a time without much trouble.
Firefox is the best for plugins/seo type things but google chrome is far out doing all of them by sheer simplicity... just wait till they allow cool plugins like seoquake!
I like FireFox the best, but I think Chrome will be just as good in a few years... Until then, Firefox all the way!
Firefox for me. I used Chrome for a while, and it was good, but the lack of addons like firefox turned me away, so I'm with firefox.
