I've configured the GPO to enable NTLM authentication for a specific site: Computer Configuration --> Policies --> Administrative Templates --> Mozilla --> Firefox --> Authentication --> NTLM

I apply this GPO to the local Win 10 Pro machine with Firefox 60 installed - GPUPDATE /FORCE

when I check HKLM --> SOFTWARE --> POLICIES --> MOZILLA --> FIREFOX --> AUTHENTICATION --> NTLM I see the site I added via GPO

however when I check the prefs.js file I cannot see user_pref("network.automatic-ntlm-auth.trusted-uris")

Those changes would not show up in the users prefs.js file - they are configured internally by the policy code.

You can go to about:config to verify that they are set.

thank you, however when I try and add the GPO to

User Configuration --> Policies --> Administrative Templates --> Mozilla --> Firefox --> Authentication --> NTLM

it does not appear in the about:config

I just tested and it is working for me on Firefox 60 32 bit and 64 bit.

When I search about:config, I see

network.automatic-ntlm-auth.trusted-uris and it is set and locked.

What version of Firefox are you using?

I'm using 64 bit Firefox 60. it seems to work very well when using Computer Configuration, but just not for User Configuration.

I can see the Registry entry under HKCU but it just seems to not appear in about:config

Many thanks mkaply. Your initial response resolved my question.

My second problem was a result of not removing the Computer Configuration GPO and applying the same User configuration GPO - of course the Computer configuration GPO will take precedence over User Config GPO.

It's good to know that is working properly :)
