Comment (by mcs):

 Kathy and I can not reproduce this bug when Tor Browser is running in
 multiprocess mode. When multiprocess mode is enabled, we always see a tab
 crash, which is #21766. Also, if the pref
 `extensions.torbutton.launch_warning` is set to false, neither this bug
 nor #21766 occur.

 I wanted to mention our experience in case someone is seeing different
 behavior.
