Does what it says on the tin, with no unexpected side effects.
(to those who complain about not being able to use their facebook login on other websites: this is expected behavior and explicitly mentioned in the description!)

Addon works as expected, but I don't understand why it has to be a separate addon when you could simply add a clickbox to every container to work like this. I would like to isolate more websites than FB.

REALLY GREAT TOOL!!! CONGRATS!! ;-)))

Can't login with Facebook on certain websites and won't allow me to manually whitelist said websites either.

Good in defending the user from being track in some situation

good!

breaks every websites that use FB login, why can't I manually assign sites to use this container?
