A client requires us to test MAC and PC firefox 4.0, however I can only find installer for FF5 and FF3.x on the site. Where can I find FF4 installers? Thank you

Firefox has moved to a rapid release schedule and is removing user-facing version numbers. New versions will release every six weeks. Essentially, FF5 was a stability fix. Under the old numbering regime, it would've been considered 4.1.

It's your call, but I wouldn't bother to test separately.
