Comment (by tom):

 No, the pref should be enough. I was suggesting revert the other one to
 carry one less customization.

 Policy support will be screwy though. As this issue illustrates, if you
 enable policy support, you will pick up a policy for Firefox, if it's
 present in certain locations, rather than a Tor Browser-specific policy.
 If we wanted to support policies we probably should require them to be TB-
 specific.
