I can't complain about the add-on itself, because I use a bunch of others extensions similar to Container (all aimed at privacy). Also, it's quite simple to understand what it does and everything is explained when you hit the add-on button next to the address bar.
If you're concerned about your privacy against Facebook's practices, it's a good choice, because you just have to install it and surf the web hehe.

works grate
