Try using the Add-on Compatibility Reporter to override compatibility.

Firefox 4 versions aren't supported by security updates that are included in Firefox 5.0 and Firefox 3.6.18. If you are gonna "go back", use 3.6.18 instead.

You can find all of the previous releases of Firefox here:

ftp://archive.mozilla.org/pub/mozilla.org/firefox/releases/

Just click on the folder for the version you want (in your case "latest-4.0") and then select your OS and desired language. You'll find the installer for that version there, ready to download and install.
