Enabling NTLM Authentication in FireFox

I’ve been looking for a solution to enable NTLM authentication in Firefox that won’t require manual entry per user. I’ve found VB scripts that can do this when set up in group policy but the IT team responsible for intranet sites and development would rather have me do it in PowerShell if possible.

I’m not 100% certain where to start but I’m guessing that it will require modifications to be made to prefs.js? I know I could write a script to add to that as necessary, but I want to make sure that it’s the right place to start.

Has anyone ever done this before/have any advice?

TD;DR: we’re looking to automate a passthrough of current Active Directory user credentials to intranet sites in Firefox. Is prefs.js the right starting point?

Thanks in advance! :slight_smile:

I would suggest starting here and using a configuration file for Firefox, then it is just a matter of pushing it out to your machines. Once the config file is on your machine it will override preferences, and I believe NTLM is one of them you can set. I use group policy to push out the configuration file.
