Firefox won't update - tho I have OSX 10.5.8 it keeps saying I have too old an OS. The auto-update for Firefox is greyed out. How can I update?

more options

I have a Mac Powerbook G4, running OS X 10.5.8. I'm getting messages from Google that Firefox is an old version and needs updating - so I went to the Firefox website and the message said that "Unfortunately the latest version of Firefox isn't compatible with your computer's operating system. Learn more." When I click Learn More, it says that Firefox only works with OS X 10.5 and 10.6...The auto-update box for Firefox is greyed out and un-clickable in Firefox preferences, there's no manual download that I can find - how can I make Firefox recognize my OS and allow me to upgrade? Many thanks.

PPC Macs aren't compatible with Firefox 4.0 and later versions.

For older Macs that aren't supported in Firefox 4 / 5 / 6, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .

Or use Firefox 3.6.22.

Thank you - will try the tenfourfox. Already have the old Firefox; hence all the warnings that I'm working on an old version...

Those warnings aren't about Firefox 3.6.22, which is still supported by Mozilla. The Firefox 3.0.5 version you posted here with went out of support a couple of years ago, hence the warning you received.
