If you are an android user then you must be familiar with the Chat heads of Facebook Messenger on your device. Faces.im brings you the similar interface to your PC with a Chrome Extension.
Faces.im is a simple Google Chrome extension where you have to login with your Facebook credentials and you will start receiving a chat head notifications with the user’s profile and the message contained with it. Yes just like the Android’s Facebook Messenger Interface.
Although it is similar to Android’s Facebook Messenger Chat heads, it does not show messages as a drop down list when clicked on the head. Instead it opens up a new tab with the Facebook Message. You will be able to receive messages on any tab unless you disconnect your Facebook account from the Chrome app.
