Comment:

 Replying to [comment:6 tom]:
 > I did find another way to control this besides the policy file. I
 believe that we should revert #29445, set
 browser.policies.testing.disallowEnterprise to true, not support enteprise
 policies in any way shape or form, and test a release and alpha build to
 ensure the proxy can't be bypassed.

 Hm, so `browser.policies.testing.disallowEnterprise` set to `true` *alone*
 does not solve our problems here? Or is it just too risky relying just on
 that pref alone? Because *if* folks know what they are doing and want to
 have policy support why not allowing that feature? If the pref alone is
 not enough that sounds like a bug with the pref handling which should get
 fixed independently of this ticket.
