Facebook Desktop will ask you for permission to connect to your Facebook account and send you notifications when necessary, basically, Facebook Desktop will let you know if you receive:
- New messages.
- New messages on your wall.
- Notifications of new friends.
- New pokes.
Facebook Desktop doesn't really allow you to change hardly anything on Facebook, but it can come in very handy to let us know when there is movement in our account, so that we can access it at that moment.
Facebook Desktop will stay open in the system tray to check every minute if there is any new activity on your Facebook, but if we open it, we'll find a summary and the links necessary to organize our account on this social network.
