The website may try to fallback to TLS 1.0 in a way that is no longer allowed in current releases or may be using a deprecated cipher suite.

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 ( 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 (,

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