Facebook Messenger is a new application that lets you use Facebook without being on www.facebook.com.
While you surf the web or use other applications on your computer, you can:
Chat and message with your friends on Facebook
See and respond to chats right from your desktop. Whether you're browsing other websites or using another app, you don't have to click away to stay connected.
See the latest updates from your friends in Ticker
Get quick Notifications about what’s going on
Find out about new comments, photo tags and more as soon as they happen.
