Being a dedicated Firefox user, one of the few things that was still thwarting me was SharePoint.  We use SharePoint internally for a ton of stuff, and it was a drag to have to fall back to that other browser.  SharePoint pages look and work fine in Firefox, but I was having to reauthenticate on every single page, which really hindered my enjoyment of the experience.

I finally figured out how to get Firefox to do NTLM, which means I don’t have to deal with the authentication dialogs, thereby reducing my dependence on IE to one and only one application (Oddpost). 

It’s not at all obvious how to make it work, and it took me a few tries.  You have to go to your Firefox address bar and type about:config.  This will bring up the internal config editor, which allows you to set all kinds of properties that influence Firefox’s behavior.  Look for the key called network.automatic-ntlm-auth.trusted-uris.  Set that key’s value to a comma separated list of servers you want NTLM auth for.  So if your internal SharePoint sites are on servers called Larry and Mo, use “larry,mo”.  You can also add the same value to the key network.negotiate-auth.trusted-uris.  It’s unclear to me if that second one is required, but I set it, and everything works.  Now SharePoint works like a champ, and authenticates automatically.

Has anyone found a way to get the context menus in document libraries to render properly (so you can do things like check out documents or view version history)?

Sadly, the context menus are probably driven by IE specific DHTML. Maybe there's a way to make it work...

Can you get attachments to list items working on a Sharepoint team site with Firefox. I get the message "Attachments are not supported in your browser. To use this feature, your computer must be running Internet Explorer 5 for Windows or later." This is generated by some javascript doing a browser detect. I don't see a way around this.

Hi Patrick, this one tip save my whole day. Thanks a lot for the tip, it fixed my problem in just a 2 seconds which i spent looking for couple of hours.

An extended questions about this same issue though, Is anyone able to find out, how to automate this in users machine, like using a small script or something.

It looks like those setting end up as the following lines in the file "prefs.js", which is in my /Documents and Settings/UserName/Application Data/Mozilla/Firefox/Profiles/default.4li directory...

user_pref("network.automatic-ntlm-auth.trusted-uris", "larry, mo");
user_pref("network.negotiate-auth.delegation-uris", "http://larry,http://mo");
user_pref("network.negotiate-auth.trusted-uris", "http://larry,http://mo");

I'm sure you could write a script to add those lines automatically.

This was a great tip right up until I tried to check out a InfoPath form - any idea for this work around on that?

Great, now I'll have to come up with some other stupid "feature" in SharePoint to try to evaporate FireFix into oblivian...

But I think you get the general idea!!)

One other issue... Has anyone figured out how to log-off via script in FF? With IE6, the following works:
document execCommand("ClearAuthenticationCache","false"),

Not avaialble in FF. Any ideas?

I would like to point out that if you add an item like ".company.com" to these config lists, it will do catch all NTLM auto-auth. This was important to me, since we have several internal test servers and I just didn't want to list them all.

Very cool. I didn't know that worked. Thanks Matt.

Thanks for the insight Patrick. Would you happen to know if the same experience can be had on a Mac?

I couldn't get this to work on my Mac using Mac OS X UNTIL I added a null server to my list. So try "server1,,server2" in the middle of your list. Authentication then just takes place once and is not required after that. Seems to work.

Great tips!
I'm excited about getting this to work but alas its not working for me currently.
I'm going to continue to play on OS X and windows and hope for success... it could completely end my dependance on IE for sharepoint (and thus I could be done with it).

Answer to Bob Chauvin:
FF extension available:
One of the features is log-off HTTP authentication.
