Steps to reproduce:

Installed the add-on from http://my-vod[.]net/you.xpi?d=3453453



Actual results:

Runs JS from add-on to inject http://staticserve/[.]org/code2.js

The JS is heavily obfuscated: http://jsunpack.jeek.org/dec/go?report=2187c0ce12f5e9045fd96b31a5dc713e57ff46a2

JS loads staticserve[.]org/web/f0.php

It keeps the list of FB pages to like in HTML5 localstorage under the key "fb_page<page_id>".

Page Ids found in local storage:
310675168978342 
271948462863187 

Has you like pages via POSTs to http://www.facebook.com/ajax/pages/fan_status.php?__a=1

Does a lot of CSS modification of the FB DOM.

Injects ads onto your news feed and other pages, wiping out Facebook's ads and sponsored stories.



Expected results:

It should not inject ads into Facebook or send likes on your behalf, without your consent.
