nit: can you put proxy-config-url second, i.e.

  $('proxy-config').disabled = $('proxy-config-url').disabled ||
                               !$('proxy-config-url').checked;
  $('proxy-config-url').disabled = $('auto-proxy').disabled ||
                                   !$('auto-proxy').checked;

same here, can you put proxy-config-url after, like this:

  $('proxy-config').disabled = true;
  $('proxy-config-url').disabled = true;

       $('proxy-config').disabled = true;
     },
   };
