Comment:

 Okay, I tried for a while to set up a testing environment on my local
 computer and have the group policy editor used to lock down the proxy
 configurations in Firefox. However, this policy is neither applied to
 Firefox nor Tor Browser for me. I took the policy templates from
 https://github.com/mozilla/policy-templates/releases and copied them over
 to C:\Windows\PolicyDefinitions and then started the policy editor and
 activated the proxy option. What else do I need to do to get this going?
 Do I need some other tool making sure the respective users are under that
 policy or what am I missing here?
