i'm going to take behind what's behind this door number win.
Firefux if you want a lot of features (extensions)
Chrome if you want faster program response (because firefux takes a while to start)Fail blog material.
If you want speed: Firefox
If you want to add whatever extra feature you want: Firefox
If you want a browser that isn't as ugly as sin: Firefox
and really, Firefox's default skin is ugly as sin, especially on Vista/Win7. Also, Chrome is proven to be faster than Firefox.
and Firefox has nice skins though, and Chrome? Fast? Not on my computer.
