     20 // were blocked, and the user can click one to get a bubble hosting a few
     21 // controls.  This class provides the content of that bubble.  In general,

     23 // the blocking settings for the current site, a close button, and a link to
     24 // get to a more comprehensive settings management dialog.  A few types have
     25 // more or fewer controls than this.
