Hey, this is awesome! So much nicer than using Firefox’s save password functionality. If I’m logged into a domain, and the website is on IIS with all that “windows auth” magic that automatically lets you in when using IE… well… I get that functionality in Firefox!
Thanks to Eric Wise!
basically, just add hostnames for which you wish to allow this type of authentication (a little more work than IE, a lot more security) to the following preferences in about:config : network.automatic-ntlm-auth.trusted-uris, network.negotiate-auth.delegation-uris, network.negotiate-auth.trusted-uris.
