Entrepreneur and hacker Nik Cubrilovic reports that Facebook can track the web pages you visit even when you are logged out of Facebook.

According to Cubrilovic’s tests, Facebook merely alters its tracking cookies when you log out, rather than deleting them. Your account information and other unique identifiable tokens are still present in these cookies, which means that any time you visit a web page with a Facebook button or widget, your browser is still sending personally identifiable information back to Facebook.
