commit 76fd8eba75bf4215041d4a11f4e06faa175f0005

    Bug 40036: added a test to check that permissions are not saved on storage
    
    In our Firefox patch set we have a test that assures that preferences
    are kept in memory, instead of saving them to the disk or other
    storage.
    However, usually we check this kind of functionality here, not on
    the Firefox/tor-browser code.
    
    Other tests in that tor-browser commit should already be covered.
