I have downloaded Firefox 4.0.1 onto my power PC G4 mini using mac OSX version 10.5.8. When I try to open this new version I am told “You cannot open the application Firefox because it is not supported on this architecture. What can I do? Do I have to go back to the old version? Thank you for your help.

Firefox 4 doesn't run on a PowerPC Mac.

Firefox 4 requires at least OS X 10.5 and an Intel Mac.

For an unofficial Firefox 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:

Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:
