Yes, it probably would be dangerous to be able to modify it, but it would be nice to read it! On my “DualLogin” page (ASP.NET, C#) I display a “Use Windows Credentials” link which allows domain users to login without submitting username/password explicitly (it then verifies automatically passed username against application’s database and uses FormsAuthentication.RedirectFromLoginPage().
I’m displaying that link only for internal users (IP check) and, currently, only for IE users, because I don’t want that automatic authentication pop-up. If it was possible to read network.automatic-ntlm-auth.trusted-uris settings, I would display this link for some Firefox users as well…

I am not sure if you can do that from Javascript. You might need to Google a bit on that one. I can see that might be handy, but maybe there are security implications allowing access to some of that data in about:config.

Thanks for the comment! (and question)

Is there a way to read about:config (network.automatic-ntlm-auth.trusted-uris) settings from JavaScript? (Or maybe from HTTP headers in a server-side code?)

Quite important though, the comma seperated list is actually comma and space seperated. It didn’t work at first, until I put a space after the comma.

Oooh, this is nice :) Now I can use Firefox (without IEtab) for our company intranet! Thanks! I always, like you, assumed that automatic Windows Authentication was unavailable for Firefox :O

about:config is like a Mozilla “registry” of settings builtin to it. You get to it by typing that directly in your URL address bar. Like you are browsing to it.

Where the heck is about:config? Firefox 2.0.

Someone left a comment and I think I bulk deleted it on accident. Whoever you are, sorry about that. If you like, post again, I’ll remove my comment.

Anyway, your comment on adding multiple sites is a good point. So to add more than one site to this list, just use comma separated list. (site1.com, site2.net, etc)
