Steps to reproduce:

A malicious add-on, named "Youtube Speed UP!" is being served to Facebook users via a fake YouTube page.  The add-on sends spam to a user's Facebook friends by stealing their browser cookies.

This is similar to the "Free Cheesecake Factory" add-on we reported last week.

Actual results:

Installed add-on, spam sent from the victim's Facebook account.

Expected results:

No spam.
