  1. Start Firefox and type about:config in the URL address bar.
    A list of configuration parameters appears.
  1. Look for the parameters network.negotiate-auth.delegation-uris and network.negotiate-auth.trusted-uris:

  1. Edit both of these parameters (double-click or right-click and modify) and enter the value https://firewall_serial_number.dns_domain ( in the example).
  1. Close the browser to confirm the configuration.
