How do I know if Facebook Container is working?

Affected Facebook features
Facebook Container prevents Facebook from linking your activity on other websites to your Facebook identity. Therefore, the following will not work:
- “Like” buttons and embedded Facebook comments on other websites Because you are logged in to Facebook only in the container, “Like” buttons and embedded Facebook comments on other websites will not work.
- Logging in or creating accounts on other websites using Facebook Websites that allow you to create an account or log in using Facebook will generally not work properly.
