ok, unfortunately that error isn't very specific that would point towards any direction or known workarounds. firefox recently dropped support for some cypher suites and encryption mechanisms as there were vulnerabilities discovered and they are no longer considered secure. other browser will likely follow suit in this field and may not work much longer either. so it would be best to raise that issue with your IT department for investigation...

Thanks. I am in the IT department. I prefer FireFox, but we are in the process of testing out the newest versions of IE and Chrome with all security settings. I guess this is probably the reason we are not testing FireFox... I'll just have to switch. Thanks again.

You can open the about:config page via the location/address bar and use its search bar to locate this pref:

  • security.tls.insecure_fallback_hosts

You can double-click the line to modify the pref and add the full domain (TEXT) to the value of this pref. If there are already websites (domains) in this list then add a comma and the new domain (no spaces). There should only be domains separated by a comma in the Value column (example.com,www.example.com).

If this helps then you can contact this website and ask them to look into this and update their security.
