Nik Cubrilovic claims that the social network can find out what web pages you visit with its tracking cookies.

Australian entrepreneur, writer and hacker Nik Cubrilovic has written an interesting post on Facebook's ability to track its users even when they are no longer logged onto the site. In Logging out of Facebook is not enough, he states:

Facebook are only altering the state of the cookies instead of removing all of them when a user logs out. With my browser logged out of Facebook, whenever I visit any page with a Facebook like button, or share button, or any other widget, the information, including my account ID, is still being sent to Facebook. The only solution to Facebook not knowing who you are is to delete all Facebook cookies.
