I've read your recommended work around, that said to trash all previous versions of Firefox, I've done so and now have no browser other than Safari.

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

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:
