Some versions of Firefox do not automatically trust all servers to send transparent credentials to. The newest versions appear to be having the problem.
You will need to manually add the WSA transparent authentication redirection hostname into the trusted URLs in Firefox. This value can be found in Network -> Authentication -> “Transparent Authentication Redirect Hostname”
1. Open Firefox and type “about:config” in the address bar (without the quotes) 2. In the ‘Filter’ field type the following “network.automatic-ntlm-auth.trusted-uris” 3. Double-click the name of the preference that we just searched for 4. Enter the Transparent Authentication Redirect Hostname
