 Until Tor Browser 5.5, I used to perform the following steps after
 installing it:

 cd tor-browser_en-US/Browser/TorBrowser/Tor/
 chgrp net tor
 chmod g+x tor
 chmod g+s tor

 I have a group called "net" and my iptables rules only allow outbound
 access to that group.

 Starting with Tor Browser 5.5, the following error shows up after
 performing those steps and trying to start it:

 Tor unexpectedly exited. This might be due to a bug in Tor itself, another
 program on your system, or faulty hardware. Until you restart Tor, the Tor
 Browser will not able to reach any websites. If the problem persists,
 please send a copy of your Tor Log to the support team.

 Restarting Tor will not close your browser tabs.
