I downloaded by accident a later version of firefox than my Mac will run - 4.0.1. How can I get the older version back?

I have a Mac OS 10.4.11. I had a glitch while I was trying to register to a new WordPress and that site sent me to Firefox and told me to download. Before checking compatibility with my operating system, I download and put it in my applications folder. When I tried to open Firefox, I got a message saying 4.0.1 wasn't compatible with my computer.

I NEED THE OLDER VERSION OF FIREFOX compatible with my Mac. PLEASE SEND IT TO ME. Thanks.

You can download Firefox 3.6 here: http://www.mozilla.com/firefox/all-older

Before reinstalling it, I recommend backing up your Firefox settings in case something goes wrong. See Backing up your information. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
