Do you know how to use Windows Integrated Authentication in Firefox?
  v1.0 Posted at 3/02/2016 6:56 AM by Tiago Araujo

Internet Explorer has a great feature that you hardly notice. The Authentication credentials of the current user will be used by default.

In Firefox, if you sign-in to an internal server like SharePoint or CRM, you will get an authentication dialog. Even though you are already authenticated to the local domain.

The Solution

​​​
  1. Open Firefox
  2. Go to "about:config"
  3. Click "I'll be careful, I promise!"
  4. Enter in the Filter box above: "network.automatic"
  5. You see 2 records
  6. Double-click the second one - It is the key called network.automatic-ntlm-auth.trusted-uris
  7. Enter the servers delimited by ",", e.g. "aphrodite, mermaid"
  8. Close browser and test

More info on this blog: Firefox and Sharepoint.

Tip: To test this without the Integrated Authentication enabled, you need to clear your session. You do this via: Tools | Clear private data | Authenticated Sessions.
