How do I get firefox 4 back

Visit this site for FF 4: http://fileforum.betanews.com/search?s=firefox+4&x=11&y=11

Or enter which version you want in the search box

They've stopped support updates (including security) for 4 already. Rumor has it 3.6 will be updated until August.

I'm back to 3.6 now.
