Firefox and Integrated Windows Authentication

If you need to use Integrated Windows Authentication for any apps, Firefox will prompt for a username/password before displaying anything. To stop this behaviour then you need to amend the “about:config” settings in Firefox.

1. Open Firefox
2. In the address bar type: about:config
3. After the config page loads, in the filter box type: network.automatic
4. * Modify network.automatic-ntlm-auth.trusted-uris by double clicking the row and enter the site address you are using, for example “http://localhost“
5. Multiple sites can be added by comma delimiting them.
6. To specify all subdomains use .replacewithyoursite.com .
