While social plugins appear on other websites, the information appearing in them comes directly from Facebook—so they’re just an extension of your Facebook experience. Plugins were designed so that the website you’re visiting receives none of this information.

You only see a personalized experience with your friends if you are logged into your Facebook account. If you’re not already logged in, you’ll be prompted to log in to Facebook before you can use a plugin on another site.

At a technical level, social plugins work when external websites put an iframe from Facebook.com on their sites, as if they were agreeing to give Facebook some real estate on their websites. When you visit one of these sites, the Facebook iframe can recognize if you’re logged into Facebook. If you’re logged in, it’ll show personalized content within the plugin as if you were on Facebook directly. Even though the iframe is not on Facebook, it’s designed with all the privacy protections as if it were.
