Tried to upgrade a IBook G4 to FireFox 4.0 and could not make it work, is 4.0 not supported on this older machine?

Per instructions I tried to upgrade to FireFox 4.0 on my older iBook G4 and would not open. The FireFox logo had a white circle imposed on it. I was really stuck with the older version gone, and the newer one would not work. I managed to copy an older version of FireFox from another machine. Funny thing is that after loading the copy, I was still asked to upgrade to 4.0. All of this was very frustrating.

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox

The latest official version to run on OS X 10.4 is Firefox 3.6.16 available from http://www.mozilla.com/en-US/firefox/all-older.html

Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com
