I have a MAC OS X 10.4.11. I downloaded Firefox 4.0 and when I went to run it, it says "can not run with current version of OS X".

I need to either get to run 4.0 or to run the Firefox version I way previously using. I am at a loss and really would appreciate help to get back to Firefox.

Thanks, Don Costanzo

You can get an unofficial, community-supported version of Firefox for 10.4 here:
