Disables/Hides fb social activity buttons (like, comment, share, add etc)
Prevents clicking of social activity buttons when stalking people on fb.
When clicked on, it disables like, comment, share, add friend, post on timeline etc buttons and removes your hanging comment inputbox under posts.
You have to press the icon for each fb tab you want to secure.
It can handle multiple tabs at the same time.
(So, if you want to return to normal, just open a new tab)
