 I suspect that did not work? I guess you could try selecting the SOCKS
 proxy option (instead of the HTTP/HTTPS one) in that case.

 But either way, I think the underlying bug is that Tor Browser is affected
 by this Firefox policy at all and its proxy settings can get changed that
 way (even if it seems to fail closed). I try to figure out what's up here.
