permissions: -rw-r--r--

Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.

 // # Test for TB4: Tor Browser's Firefox preference overrides
 // Simple regression tests to check the value of each pref and
 // decides if it is set as expected.
 // TODO: Write unit tests to check that each pref setting here
 // causes the browser to have the desired behavior (a big task).
