When I try to download Firefox, I get so far and when I click on the icon, it states that I cannot open Firefox because it is not supported on this architecture. Can I use Firefox on this computer?

Beginning with Firefox 4, Macs must have an Intel x86 processor (yours is a PPC Mac) and OSX 10.5 or higher (which you do not have).

The good news is that Firefox 3.6.x still supports OSX 10.4 and Macs with the PPC Mac architecture. The bad news is that support for the Firefox 3.6.x series is likely to end in the first quarter of 2012.

You can try the third-party product TenFourFox that supports PPC Macs with OSX 10.4.11 and OSX 10.5.8. Firefox 9 version of TenFourFox is available. The product is based on Firefox released versions. All support is provided by the developer, not by this site:
