    Bug 18170: After update, only changelog tab shown
    
    When in permanent private browsing mode, always return false
    for isAutomaticRestoreEnabled. This ensures that there will
    not be any confusion inside nsBrowserContentHandler.defaultArgs
    as to whether a one time session restore will occur.
    
    Also, for consistency and in case someone looks at the pref,
    avoid setting browser.sessionstore.resume_session = true during
    browser shutdown.
    
    This bug occurred when staging was not used during the update
    process. On Windows it always occurred because staging is not
    used even when it should be (see #18292).
