Chrome: Want to keep track of the things your friends say on Facebook? Facebook Favorite is an extension that makes that easy by adding a “Favorite” button to posts so you can save them for later.
When you click the “Favorite” button on a post, Facebook Favorite saves that to a list in Chrome’s cache. You can then easily pull up those posts in either a list or grid layout. It’s not the prettiest extension, but it works well as a private way to bookmark your favourite posts.
