I downloaded Firefox 4 to replace my Firefox 3 on my Mac, but 4.0 for Mac says it will not open on my computer. How can I get my Firefox 3 version back?

Firefox just updated my Firefox 3.??? version on my Mac. Firefox encouraged me to download the new 4.0 version for Mac, so I did. However, when I try to open the 4.0 version it says that it cannot run on my OS X version (which has been updated). How can I either get Firefox 4.0 to work, or alternatively how can I get my latest version of 3.??? reinstalled. (I could not find the 3.??? version to install on the Firefox site.)

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

Firefox 4 requires at least OS X 10.5
