I upgraded to 6.02 and still get this message from Gmail: "You are using an old version of Firefox which Gmail no longer supports. Some features may not work correctly. Upgrade to new version."

When I opened Gmail in my Firefox browser, I got a message I've never seen, before: "You are using an old version of Firefox which Gmail no longer supports. Some features may not work correctly. Upgrade to new version." I clicked on upgrade to a new version and was taken to the Mozilla site, where I downloaded the latest version of Firefox... then, when I restarted my computer, Gmail still gives me the same message!! What's going on?

I have another problem - Firefox no longer supports my Mac OSX so I can't download the latest Firefox. At least not without changing my operating system. Maybe that will be bad luck for Gmail...

Firefox 4 and later require at least OS X 10.5 and a Mac with an Intel processor.

For an unofficial Firefox ESR 10.0.4 compatible version (TenFourFox) that runs on PowerPC Macs with OS X 10.4.11 or OS X 10.5.8 you can look at:

Be aware that TenFourFox doesn't support plugins.
