Hi Tom, 
 Can you try disabling TLS Delegated Credentials in Firefox and try again? 
 
 In a Firefox window, navigate to about:config . 
 Search for the &ldquo; security.tls.enable_delegated_credentials &rdquo; preference - the preference list will update as you type, and &ldquo;delegated&rdquo; is itself enough to find the correct preference. 
 Click the Toggle button to set the value to false . 
 Browse to https://www.facebook.com/ again
