I need to reinstall the older version of Firefox since 4 doesn't work with my laptop - where is it?

I updated to 4 but now it won't open. The install replaced my older version of Firefox. I can't figure out how to uninstall 4; and will that make my older version available again? If not, is it available for download on the Mozilla website?

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
