    Bug 25458: UI customization half-broken in Tor Browser 8.0a3
    
    Fixed fallout from #25147.  Some of the functionality of the UI
    Customize screen is dependent on setting innerHTML on divs.  Since the
    code runs in the System context, the HTML was being sanitized and broke
    page functionality.  The offending statements have been switched to the
    unsafeSetInnerHTML() method which bypasses sanitization in System
    context.
