Changes

::::Well, we could move extensions installation to a new single thread and live just FF v1/2/3 packages. Or even get rid of FF2, because everyone who'd like to install v2 should use v3, and if someone has an old computer might have want to use v1.5 (but I haven't checked does FF 1.5 works better than FF 2 or FF 3 on old machines)

::::: What about creating Firefox:Extensions page, and move the extensions there (both pages should link to each other)?
