I have a Mac G5 running OS 10.5.8. I downloaded Firefox 4 and now the program will not open at all. I get an error message that reads --

"You cannot open the application 'Firefox" because it is not supported on this architecture."

I am also unable to find a link to download the previous version (3.6) that was running fine. (I'm using Safari to contact you.)

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

If you prefer, you can get the latest version of Firefox 3.6 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

Same proble here, although the Firefox system requirements says it is OK to have PowerPC G3 G4 or G5 ( I have G5 2GHZ)

My solution; very simply use timemachine to restore the previous Frefox 3.x

worked great in 3 mns
