I don't know what else to tell you. a message on Firefox kept coming up and asking me to download the latest version. I downloaded the version 4 and now I can't use it. It comes up with the comment above

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

You can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
