Yes, we do this:

  exec_unconfined_firefox \
    -app "${TOR_LAUNCHER_INSTALL}/application.ini" \
    -profile "${PROFILE}"

… with a custom application.ini that contains (in Tails 3.12):

  ID=tor-launcher at torproject.org

Apparently not. With Firefox 65 on Debian, I've extracted
tor-launcher at torproject.org.xpi from current stable Tor Browser, added
the aforementioned application.ini in the same directory, and run
"firefox -app /tmp/blah/application.ini". Then I see a Tor Launcher
"Unable to start Tor" dialog and once I click through it, the "Connect
to Tor" one.

Does this mean it'll still work in Firefox 68esr?
