At the end of video played in FireFox I get an option to share video.
And I can't find any setting for this in plugin.

IS it possible this is a local feature from som local program ?
Please help me recognize this and make it go away. 

All help is more when welcome!

Need to delete:
code has:

'plugins': {
            'viral-2': {
                'onpause': 'false',
                'oncomplete': 'true'
            }
        },

Delete the above block of code from the site.  I can't remember exactly but something like source.php contains it.
