 knowing from the start** that it's running in the Tor Browser (I suggested
 by [https://dxr.mozilla.org/mozilla-
 central/rev/c2e3be6a1dd352b969a45f0b85e87674e24ad284/toolkit/components/extensions/parent
 /ext-runtime.js#117 customizing the browser.runtime.getBrowserInfo()] API
 to return something meaningful, but maybe there's an easier way) and, if
 that's the case, either repeating the "start" message every 100ms until it
 gets acknowledged or waiting for an "updateSettings" message to arrive.

 patching of NoScript, is for torbutton to keep sending its first
 updateSettings message (say every 100 ms) until NoScript responds.

 But without a further, Tor Browser specific patch for NoScript (to delay
 page loads until the updateSettings message has arrived), the first page
 load could still happen with the wrong settings.
