Why won't Firefox install on my Power Mac G5 with PowerPC 970 (2.2) running 10.5.8?

I have used Firefox on my Power Mac G5 with Processor Power PC 970 (2.2) and OS X 10.5.8 for years. Now when I try to install the latest for 10.5.8 the message says: "Not supported for this architecture"!

Can I use Firefox on this computer?

Firefox 4 versions and later do not run on a PowerPC Mac.
Firefox 4 and later require at least OS X 10.5 and an Intel Mac.

For an unofficial Firefox 9 compatible version (TenFourFox) that runs on PowerPC Macs with OS X 10.4.11 or OS X 10.5.8 you can look at:

Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:
