where from?

[Felt Lair]

I never downloaded or installed Mozilla, yet there is a Mozilla folder
on my machine.
What I did do was install Netscape 6, then almost immediately uninstall
it in favor of NS 4.7. I'm guessing that Mozilla cropped up with NS 6 --
and that it can safely done away with, using NS 4.7 -- correct? I think
it may be causing a problem or two with NS 4.7.

That's all. Just want to know if I can dump it.
