These versions have an ability to detect if the Facebook users are active on Facebook or if they are not using any cookie. In case the users are logged in and are using the Facebook account, the content gets personalized for them. The lists of friends are shown to these users who have previously clicked on the like button. In case, the users are not signed into their Facebook account, they would be asked to log in to like the page.
