i use mozilla all the time. its better than i.e as far as im concerned. im not gonna go ranting on about all of its great features because i dont give a shit. all i use it for is browsing.
i used mozilla when i had my linux redhat. i really dont see a differance in any kind of browser but actually mozilla is way better that internet explorer (made by microsoft) biggrin:
i changed when i.e kept crashing, when i.e crashes it fucks up my desktop. mozilla is good, fast, easy to install (just released a new version), works well.
I use netscape 7 which is apparently a Mozilla browser in new skins (because when I use composer it says "page created by mozilla" in the designer's notes).
I have mozilla on the Linux computer at work also.
So far both netscape and mozilla work better than latest IE
