I tried to upgrade to 4.0 but the screen said it would not run in this architecture. I assume that it is because I do not have an intel based Mac. How do I revert to 3,6?

You can get Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
