Well i installed it. Features im currently using are:
Noia Extreme 2.0
FoxyTunes
Macromedia Shockwave & Flash
Java
Firefox is cool. Wish id changed a long time ago
EDIT: Just checked the other two accounts on the machine and aslthough FF installed to my profile and i set it as the defult browser, my parents preferr to use IE. Now when i went into their accounts to change everything back that was ok. But i went back onto mine and i had IE set as the defult browser. Now how comes i cant set FF as the defult browser on mine, but it also changes on my parents accounts?
