Yep I have heard nothing but good stuff about Firefox 4. I am not IT smart but I have heard a few people say they dont like Chrome. IDK, I personally have Firefox but not the 4.0 version. Thinking of upgrading but right now I am satisfied with the version I have. IT people if I upgrade will I lose the stuff I have downloaded like Google earth and the special tool bar I now have. Its not like I couldnt re-download, I just dont want to take the time to re-do it all.
