Q&A: Turning Off a Social App I signed up for one of those Facebook news-reader apps and now it broadcasts the articles I read all to all my friends. How do I get rid of this app? You can modify the behavior of all your Facebook apps - or delete them entirely - by adjusting your Facebook settings. To get there, click the triangle for the Settings drop-down menu on the right side of the screen and choose Account Settings. On the Account Settings screen, click the Apps link in the left column to see a list of all the applications you have added and authorized to work with your Facebook account. Find the app you want to remove and click the X at the end of the line to delete it. If you want to modify an app's behavior and have it stop posting stories to your feed, click the Edit link next to the name of the app. In the settings area, make your changes to the app's ability to post and use your personal data.
