Where can I download the previous Mozilla Firefox version 3.6.4? My Mac OS X 10.4.11 is too old to run 4.0

I am running Mac OS X 10.4.11. I was running Firefox 3.6.4 and it was running fine. After I updated to Firefox 4, I can no longer even launch Firefox. I receive this error message: "You cannot use the application Firefox.app with this version of Mac OS X." I would like to reinstall Firefox 3.6.4 but I can't find where I can download it from. Any help would be greatly appreciated since Firefox is my browser of choice.

You can get Firefox 3.6.15 from http://www.mozilla.com/en-US/firefox/all-older.html

If you really want 3.6.4 (this is not recommended), the "Previous versions" section of the following link shows how to find it - https://support.mozilla.com/kb/Installing+a+previous+version+of+Firefox

Thanks a lot Tony! I am not ready to upgrade my Mac OS system yet, but I certainly want to continue to use Firefox as my web browser. I know I'm putting off the inevitable. Thanks again for your assistance.
