Cause

This behavior is by design, as Firefox rejects all SPNEGO login challenges (Kerberos, NTLM, or other authentication protocols). For more information regarding this behavior, please see the following article:

Resolution

This issue can be resolved by altering the network.automatic-ntlm-auth.trusted-uris configuration property to include the Microsoft Dynamics CRM website.

  1. In Firefox, navigate to the following URL: "about:config".
  2. If a warning page appears with the message, "This might void your warranty!", click "I'll be careful, I promise!".
  3. Locate and double-click on the network.automatic-ntlm-auth.trusted-uris string property.
  4. In the "Enter String Value" box, enter the URL address used to access the Microsoft Dynamics CRM website (ex. http://crm). Please note that multiple websites can be separated in the string value by using a comma.
  5. Click Ok.
  6. Close and re-open Firefox.
