Careful :: Facebook tracks what you do online even when you're logged out

An Australian technologist has claimed that Facebook can track the web pages you visit, even when you are logged out of the social networking giant.

According to Wollongong-based Nik Cubrilovic, when the user is logged out of Facebook, rather than deleting its tracking cookies, the site merely modifies them, maintaining account information and other unique tokens that can be used to identify its users.

This simply 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.

"Even if you are logged out, Facebook still knows and can track every page you visit," Cubrilovic wrote in a blog post.

"The only solution is to delete every Facebook cookie in your browser, or to use a separate browser for Facebook interactions," he added.
