Update Dec 2020:

Facebook has found a way to track around it, I've been getting ad's for stuff I just browsed again.

Original review:
To all the people complain it breaks other websites, that's the point of the container! It's to help stop facebook from spying on you everywhere you go, blame the broken websites for requiring facebook to log in or implementing their tracking bugs.

Review: It works great for me, every since I started using it I'm noticing a lot less targeting advertising on facebook from things I do elsewhere.
