Look, it's going to take a while. But here's what you do:
Applications and WebsitesÂ
Click on Edit Settings
Uncheck the box.
Then Facebook will tell you, via a pop-up, "Allowing instant personalization will give you a richer experience as you browse the web. " and it will ask if you're sure and if you want to confirm.
Click on Confirm.
But this still won't stop your friends from sharing information about you with those sites. To stop that, you have to block those sites one by one. To find out about that, you're taken to an FAQ page. I couldn't understand it. So I finally found this page where you can link to individual applications like Yelp and Pandora. And once you get on THOSE pages, you can click on Block Application, and then ANOTHER pop-up comes up for you to confirm.
And that's all you have to do! Of course, at the moment Facebook only has three partners in this program. What if they had hundreds? Thousands? The way things stand now, you'd have to go through and block each one of them individually.
