    Bug 3547: Block all plugins.
    
    We cannot use the @mozilla.org/extensions/blocklist;1 service, because we
    actually want to stop plugins from ever entering the browser's process space
    and/or executing code (for example, AV plugins that collect statistics/analyse
    urls, magical toolbars that phone home or "help" the user, skype buttons that
    ruin our day, and censorship filters). Hence we rolled our own.
    
    See https://trac.torproject.org/projects/tor/ticket/3547#comment:6 for musings
    on a better way. Until then, it is delta-darwinism for us.
