A friend just sent me this message:

Between today and tomorrow, the New FB Privacy setting called “Instant
Personalization” goes into effect.
The new setting shares your data with non-FB sites & it is
automatically set to “Enabled”.

To remedy :::Go to Account>Privacy Settings>Apps & Websites>Instant
Personalization>edit settings & uncheck “Enable”.
BTW If your friends don’t do this, they will be sharing info about you
as well. Please copy and re-post.
