Just so you know, Microsoft IE 6.0 is very similiar to Mozilla, however they both have their limitations. In speed tests, Microsoft IE 6.0 is faster on startup than Mozilla, while they both are similiar is speed tests as far as bringing up indentical websites, etc...all in all, what one can't do, or doesn't do very well, you can usually do better with the later.

One huge difference. Microsoft says the minimum system requirements for 6.0 include Win98 or higher operating system. Mozilla runs fine on Win95. See here for 6.0 requirements (recommended and minimum).
