The best opening line for this post will be, quoting the developer, Facebook Disconnect blocks all traffic from third-party sites to Facebook servers. Youâ€™ll still be able to access Facebook itself.
Remember those “connect using facebook” or “login using facebook” links on websites ? This extension will remove those boxes and links from web pages.
Facebook is notified whenever you visit one of the more than 250,000 sites on the web that use Facebook Connect and has a history of leaking personally identifiable information to third parties, writes Brian who developed this extension.
.. and this extension was built by a Google Engineer 😀 ( this is not an official Google extension though )Â Install the extension from here.
