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 that was already running fine. (I'm using Safari to contact you.)
