I downloaded Version 5.0 for my Mac OS X but cannot open it. Message " --- not supported on this architecture" When I downloaded 5.0 it replaced the previous version I was using. How can I get the old version back?

I downloaded Firefox 5.0 on my eMac which is running OS X. However I get the error message "----- not supported on this architecture". I need the old version of Firefox back (it was working just fine) but 5.0 replaced it. How do I get the old version back?

Sorry, it's because Firefox 4+ are only compiled for the Intel processors.

You can get 3.6.18 here: http://www.mozilla.com/firefox/all-older

Also, for possible future reference, there is a separate project for PPC Macs called Ten Four Fox. You might give it a spin when you're tired of 3.6.
