What is the latest version that will work on my "vintage" Powerbook G4 Mac Laptop running the 10.5.8 operating system and where is that download on the Firefox undating site?

The latest version of Firefox is not compatible with my Laptop, and I could not find which of the latest versions I can use.

I was trying to upload the latest version and received an incompatibility message.

You have the latest for your PPC MAC, the 3.6.24 version.

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.
