i actually agree with Wabz, although i love Firefox i seem to keep using IE for alot of sites aswell, i currently mainly use Firefox for this site and a few others but i use IE when i need a quick reference from a site or just a quick website check etc, IE loads quicker than all other browsers and opera, i used to like opera but then i found Firefox (then Firebird) and since then i've hated opera (still have it installed though) i find opera way too bulky, too many features, i prefere IE and Firefox because they seem smaller, i know Opera is 3mb to dl (non java) but im on DSL so 3mb is nothing tbh, loading times are about the same for me in ALL browsers, maybe slightly faster in Firefox and Opera but not amazingly faster...
Never tried Netscape though so not sure about it
