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.
