All data in Firebaase can be accessed by URLs. If you go to your the Firebase dashboar to view your data model (Forge) and click on the property you are interested in you would be redirected to a URL by which you can access this particular data, e.g. https://myapp.firebaseio.com/todos/simplelogin:1/-JUAg9rVemiNQykfvvHs/private. Keeping this in mind you can access this data with AngularFire.
