Steps to reproduce:

Downloaded http://123buzzbuzz.free[.]fr/content.xpi


Actual results:

Add-on name "Plugin Video"
Add-on homepage http://123buzzbuzz.free.fr

Addon contains youtube.js, which injects <script> to load http://123buzzbuzz.free.fr/g.js

g.js injects <script> to load http://123buzzbuzz.free.fr/yeah.js

yeah.js does the following
	steals the user's Facebook cookies / tokens
	grabs their friends list
	likes one of the following Facebook pages with ids "170270043065994","125634380874892","146184075465813","152559774839890","274266539251303","290925474288531","316272665054709"
	spams one from a set of text / bit.ly URL combos onto the user's wall
	all of the bit.ly URLs redirect to wholesale44.free.fr domain
	it then posts one of the same msg / URL pairs to the Facebook open graph


Expected results:

It should not steal cookies from the user's Facebook session and send messages to the user's friends without their consent.
