That toolbar will always show for Super Admins on your site. Unless you've changed the permissions (from the "Options" button in the JFBConnect admin area), no other user groups will see that tool bar. The "Social Meta" is useful to understand what open graph tags have been set on your page so that you can control the message when your pages are shared/like'd.
We are planning a 'disable' option for the social toolbar in the next major release so that it can be completely disabled if you never want to see it, even as a super admin. If you want a small code snippet to remove it entirely now, just let us know, and we can help you do that.
Thanks,
Alex
