where is this method included from?  i don't see an addition of your new
lock_screen_constants.js to /options/

I'm not quite sure where to add this file, is options_bundle.js the place to add
it?

[Dan Beam, 2016/09/17 00:36:03]

how about a <script> or <link rel=import> in browser_options.html

[sammiequon, 2016/09/21 18:22:43]

Done.

           };
           $('manage-screenlock').hidden = false;
         }
