That Facebook is not safe for privacy is known to us for sometime now .
Earlier, it was the availability of your details with your photos, without you selecting the option.
Now, ‘According to Australian technologist Nik Cubrilovic: ‘Logging out of Facebook is not enough.’ He added, Even after you are logged out, Facebook is able to track your browser’s page every time you visit a website. He wrote in his blog ’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.‘
After explaining the cookies behavior he also suggested a way to fix the tracking problem: ‘The only solution to Facebook not knowing who you are is to delete all Facebook cookies.”
