Facebook has launched a new product as part of their social plugins for third party sites. This bar loads up a box at the bottom right/left of the web page and lets the user see what their Facebook friends have recommended on the same domain.

The latest one is named Recommendations Bar.

Facebook spoke about this new feature:

Today we’re launching the Recommendations Bar, a new social plug-in that helps people find articles based on what their friends like and share from your site. As a person reads an article, a small pop-up surfaces at the bottom of the screen highlighting recommended articles and prompting them to like the page. Recommendations are based on content that friends have explicitly liked and shared in your app or website. Just as how the Like button works now, when a person likes an article using the Recommendations Bar, a story is published back to their timeline and friends’ news feed.
