Comment (by mcs):

 Replying to [comment:4 catalyst]:
 > I've seen this happen on Linux when starting Tor Browser for the first
 time after deferring a restart after an autoupdate (7.5a5 to 7.5a6,
 maybe?).  I had to quit Tor Browser completely to get it to start cleanly.
 (Clicking "Restart Tor" didn't work.)

 Interesting. It seems unlikely that we can blame AV software on Linux. The
 next time that happens, check and see if there is a leftover tor process
 (it should exit when the firefox process exits since the latter is the
 owning controller, but maybe it does not always do so).
