I need to download 3.6 firefox on my macbook pro. I currently have the 4.0 on my macbook pro. Is it possible to download the 3.6 version with the 4.0 version already on my computer?

If you want to revert to 3.6, trash Firefox 4 then download and install Firefox 3.6, available from http://www.mozilla.com/en-US/firefox/all-older.html
