    Block without returning in profile-after-change handler.
    
    As suggested in https://trac.torproject.org/projects/tor/ticket/11183#comment:11,
    I'm going to try running the HTTP helper in a second browser instance.
    The extension blocks in order that the browser won't show a browser
    window.
    
    There's probably a better way to block the function without returning,
    but for now I'm just raising a modal dialog.
