The website may try to fallback to TLS 1.0 in a way that is no longer allowed in current releases. It also uses a weak cipher suite that is not considered safe.

  • Connection Encrypted (TLS_RSA_WITH_AES_128_CBC_SHA, 128 bit keys, TLS 1.0)

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 domain to this pref. If there are already websites (domains) in this list then add a comma and the new domain (no spaces). You should only see domains separated by a comma in the value column.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
