On the heels of yet another Facebook privacy snafu earlier this week, a Google engineer has released a Chrome extension designed to prevent Facebook from tracking users who visit Web sites that use Facebook Connect. Facebook Connect is a set of APIs that Web developers can integrate into their Web pages to allow visitors to log in via their Facebook identities and share information with their Facebook friends. Web pages that employ Facebook Connect code provide data about logged-in Facebook users who visit to Facebook.
“Facebook is notified whenever you visit one of the more than one million sites on the Web that use Facebook Connect and has a history of leaking personally identifiable information to third parties,” he wrote. “Turn off the flow of your data to them!”
