 After the update to 7.0.7, I get:
 {{{
 2017/10/23 10:09:04 firefox: Sandbox: prctl(PR_SET_NO_NEW_PRIVS) failed:
 Function not implemented
 }}}
 The result is no site can be visited, and all new tabs crash with the
 firefox "Gah" message. The fuller context is below.

 On load the tor log messages are normal, but firefox says:
 {{{

 Firefox does open, but any attempt to visit a URL produces this set of
 messages:
