Facebook Messenger is an application that shows us chat heads if a person has messaged us. Facebook’s Chat Heads let you read and reply to messages when using its mobile app without leaving your news feed or whatever it is you happen to be doing in Facebook when a message arrives.
Faces.im is a Google Chrome Extension which lets you message and chat with your facebook friends with ease. To do this, you must be logged in to your facebook account and the extension to be installed.

From now on, when someone sends you a message on Facebook, you will be able to see it as a chat head in your Chrome, similar to what you had in the Facebook Messenger app on your smartphone.
