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 <b>about:config</b> 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 (webmail3.networksolutionsemail.com) 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). You may have to add more domains if there are still problems. If this helps then you can contact this website and ask them to look into this and update their security. ---- *https://developer.mozilla.org/en-US/Firefox/Releases/36/Site_Compatibility#Security *https://developer.mozilla.org/en-US/Firefox/Releases/37/Site_Compatibility#Security
