 Assuming your Windows environment has a Firefox group policy (GPO) that
 specifies e.g. using system proxy settings then Tor Browser happily
 follows that and is ignoring its own proxy settings without notifying
 users.

 What should actually happen is that Tor Browser is ignoring those Firefox
 GPO settings instead.

 This got tested with Tor Browser 8.0.8 on Win10 1709.

 Thanks to Kit Chung for this report.
