 If you download Tor Browser 4.0.2 from https://archive.torproject.org/tor-
 package-archive/torbrowser/4.0.2/, it comes with an old NoScript. If you
 go into the addons UI and update noscript by itself without updating Tor
 Browser, NoScript is able to change its defaults. For some reason, it does
 not do this upon update from 4.0.2 to 4.0.3.

 The pref in question that is concerning is
 noscript.volatilePrivatePermissions. We want this to remain true, but
 updating noscript caused its new default value to become false.

 There are two issues here: First, what is the best way to switch this pref
 back to true for our users? Can we simply update our extension-
 overrides.js file for this pref for update?

 Second, what caused this discrepancy to happen? How do we prevent it in
 the future? Now that we have an updater, should we disable updates for
 NoScript and HTTPS-Everywhere in 4.5?
