Keep Facebook from disclosing your personal information to their "partners."

You can complete the whole process in a few minutes using the links below and your browser’s ‘back’ button. Here is how:

1. First, log into Facebook in a new window or tab.
2. Next, go to the "Instant Personalization" page (under Account/Privacy Settings/Applications and Websites) and uncheck the "allow" box. 
3. To prevent the third parties from accessing your information through your friends who have not opted out, you need to visit Pandora, Microsoft, and Yelp and click on the "Block Application" link in the upper left corner of the page.

Finally, check Facebook's “Help Center” frequently to see an up-to-date list of applications that need to be individually blocked to maintain your privacy.
