Don't restart tor after exiting the Unsafe Browser
The current rationale for restarting tor there is:
# Restart Tor if it's not working (a captive portal may have prevented
# Tor from bootstrapping, and a restart is the fastest way to get
# wheels turning)I think that is:
- risky: any tor restart outside of Tor Connection's control can cause trouble
- useless: after using the Unsafe Browser to connect to a captive portal, the user will supposedly retry connecting to Tor in Tor Connection
