Overview

Most people don't realize it, but Firefox will do NTLM (Windows pass-through) and SPNEGO (Kerberos, etc.) authentication just like Internet Explorer. Some people solve the issue by going around Firefox and hosting IE right in Firefox. The other way to do it is to keep Firefox as the rendering engine and tell Firefox it's OK to use Windows credentials to authenticate with a given site.

The problem is that managing the list of sites you allow Firefox to pass-through authenticate with is not straightforward and involves manually manipulating configuration settings.

This add-on makes it easier to manage this list, allowing you to stick with Firefox but still use integrated/pass-through authentication.

Releases for this add-on can be downloaded from Mozilla. You can learn about where the add-on is going by checking out the ProductRoadmap.

NOTE: This add-on does not actually DO the authentication. Firefox itself already has built-in NTLM (Windows pass-through)/SPNEGO authentication, it's just not obvious how to get it to work. This add-on makes it easy to configure Firefox to use its already-existing features, but it does not do the authentication proper.

Prior to version 1.0.3 the add-on was in beta and, unfortunately, experimental add-ons don't seem to be auto-updated, nor can you get updates from Tools->Add-ons->Find Updates. Version 1.0.3 was approved for public release and if you got that version, you should start getting automatic updates. for users of earlier versions you'll need to visit Mozilla and manually update.
