These versions are not secure for general web browsing, but if you are confident that you won't wander out on the web, you can pick up obsolete, unsupported, insecure versions of Firefox on the FTP server:

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

If you want to run a current version of Firefox for day-to-day use and have an old one around just for the work site, consider using the Portable version of the old Firefox.

It works for me in Firefox...which maybe isn't that helpful to you. Which browser are you using? Do you get an error that the server is not found, or some other error?
