Getting Firefox to pass Active Directory credentials to Microsoft SharePoint 2007

Here’s a simple pointer you can use when using Firefox with Sharepoint 2007 that makes life much easier.  The first thing you will notice when visting your Sharepoint site will be a pop-up box asking you to login.  This is because by default Firefox won’t pass NTLM credentials like Internet Explorer does. You have to specify trusted URLs that Firefox will pass credentials to.  In the pop-up box, you will see the site or server name it’s trying to authenticate against.  Just use your mouse to highlight this and press Ctrl + C to copy.  Cancel the login box and in your address bar, type the following:

about:config

These are the advanced settings for Firefox where you can customize pretty much anything on the browser.  Click the “I’ll be careful, I promise!” button and scroll down until you find:

network.automatic-ntlm-auth.trusted-uris

Double click on it and press Ctrl + V to paste your URL.  You can add more URLs by seperating them wite a comma like this:

http://sharepointsite1, http://sharepointsite2, http://sharepointsite3

Now trying navigating to your Sharepoint site and it will automatically login.
