Comment:

 I assume "Trap Number" refers to a signal. If that is true, then it looks
 like a SIGALRM caused the thread named "Shutdow~minator" to exit (that
 thread name must be truncated). I know that Firefox had problems with the
 firefox binary not exiting quickly enough after an update was staged and
 the user requested a restart, so I suspect this is related. This code
 looks like the culprit:
 https://dxr.mozilla.org/mozilla-
 esr52/source/toolkit/components/terminator/nsTerminator.cpp#368


 Do you know what was happening right before the crash? Had you requested
 the restart, and is it possible it took more than a minute for firefox to
 exit?

 Is there anything interesting under TorBrowser-Data/UpdateInfo, e.g., in a
 log file?
