I am running a Mac G5 with OS 10.5.8. I downloaded FF4, won't work on "this architecture" -- so what "architecture" will it run on? Normally a new application lists the requirements, but FF4 says "all apps, all computers, all everything."

I'm really angry about how this is working (or not working, actually). And every time I get a message from FireFox to "click here to do. . " it won't connect.

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

Ah! The Intel Mac. Would have been so nice to have that information in the download message. So, back to 3.x for me. That may be the end of FireFox in this office.
