Oh crap, I didn't get back to you, did I? My office machine took a dump and I couldn't get my organissimo email. All's well now.
Anyway, what problems are you having with Mozilla? The file, I believe, is a .bin file which must be expanded with something like Stuff-It Expander before you can install it.
Does that help?
BTW, I'm surfing the site right now on a new PowerBook G4. It's sweet!!! Too bad it's not mine!
