I'm not exactly sure what the problem is here; this sounds like a question for the folks at rapidshare, Speed Download, or maybe check out the MozillaZine forums.
Oh, and fully expect at least two to three other MacRumors members / mods to come on this thread and bitch you out for mentioning something that has the potential to be used for piracy. This is not the site to discuss such things on (even when used 100% legally) apparently...
