I downloaded an upgrade to Firefox 4 but it isn't supported by MacOS X 10.4. The upgrade replaced my old version. How do I get back to version 3 of Firefox? It won't open at all now.

Firefox 4 requires at least OS X 10.5 and an Intel Mac. 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

If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
