JavaScript Firebase: Query Snapshot Always Null

When you execute a query against the Firebase Database, there will potentially be multiple results. So the snapshot contains a list of those results. Even if there is only a single result, the snapshot will contain a list of one result.

Your code needs to handle the list, by using Snapshot.forEach():

firebase.database().ref().child("users").orderByChild('facebook_id').equalTo(fbID)
.once("value").then(function(result) {
    result.forEach(function(snapshot) {
        console.log(snapshot.val());
        console.log(snapshot.child("onSite").val());
    });
});
