FireFox NTLM Authentication – Windows Authentication

Maybe its just me, but having to switch between Internet Explorer and Firefox to access Internal and External sites is a hassle.  Particularly the SharePoint based sites on Firefox.

So iv found a solution ..  If you want to use FireFox for all sites heres what I did to get it working.

In FireFox

Enable auto NTLM authentication for the internal sites that require domain accounts.

  1. Open FireFox and type about:config hit enter
  2. In the filter box type NTLM , find the key -  network.automatic-ntlm-auth.trusted-uris
  3. Add a comma separated string of URLS here .. Example http://intranet,http://somelocalsite,http://sharepoint
  4. Restart firefox

When you visit these sites now, you will be authentication in the same way you are with Internet Explorer without being prompted to login.  This is absorbed from your domain account.
