I had Firefox version just before the new 8. The icon for the new version has a circle with a crossbar. The application will not open. I want to get my old version back. How?

Beginning with Firefox 4, Macs must have an Intel x86 processor; your system is a PPC Mac.

The good news is that Firefox 3.6.24 still supports 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. Firefox 8 version of TenFourFox is available. The product is based on Firefox released versions. All support is provided by the developer, not by this site:
