 caught and reported at in the `try { bindPrefAndInit(...) }...` part.
 Note: the anonymous error callback function is called asynchronously,
 which means it will only run after `start()` returns.

 Ok, yes. This means that `syncDisaplayWithSelectedTab(true)` is called
 even if it (later) turns out we would not have needed that due to the
 error handler getting called. Seems to be the price for having
 asynchronous things which is okay to me.

 With two more things addressed I am happy::

 -`if (line.match(/^\d\d\d /) && ` should get rid of the whitespace (git is
 complaining about)

 -If one clicks on "New Identity" and toggles the pref afterwards weird
 things are happening while Tor Browser complains about
 `gBrowser.tabContainer` being undefined:
 {{{
 20:30 < arthuredelstein> I guess the whole tor-circuit-display.js file is
 tied to
                          the current chrome window. With New Identity we
 destroy
                          that window and create another. But the
 preference binding
                          for the old chrome window is still hanging
 around. So when
                          you toggle the pref, it's looking for the old
 gBrowser's
                          tabContainer and not finding it.
 }}}
