$firebaseSimpleLoginProvider not found - firebase

Question

I'm having trouble getting the facebookSimpleLogin angularfire service to be dependency injected into one of my angular js services.
angular.module('cakethursdayApp')
.service('FacebookAuthService', function FacebookAuthService($firebaseSimpleLogin) {
......
});
I am getting the error "Error: [$injector:unpr] Unknown provider: $firebaseSimpleLoginProvider <- $firebaseSimpleLogin <- FacebookAuthService"
I have my scripts loaded in the following order
<script src="bower_components/firebase/firebase.js"></script>
<script src="bower_components/firebase-simple-login/firebase-simple-login.js"></script>
<script src="bower_components/angularfire/angularfire.js"></script>

Generally speaking when you have a "missing dependency" always take a look at your module declaration's dependency injection.
angular.module(modulename, [list of dependencies to inject]).
Anytime you're using firebase (with angularfire I know specifically) you'll want something like this
angular.module(modulename, ['firebase'])
Additionally (often times you'll need it) in your controller definition as well.
function myCtrl($scope, $firebase)
This way when you want to setup a reference to your firebase URL it'll look like this:
var FB = "https://##instance##.firebaseio.com/"; //your Firebase address
var ref = new Firebase(FB); // Creates a new instance of AngularFire
$scope.variableNames= $firebase(ref); // the angularfire "firebase" service reference.
(please correct me if my comments are wrong up there, this is my understanding of the code)
for use in ng-repeat or other operations
(For Example)
<div ng-repeat="variable in variableNames">
{{variable}}
</div>

You need to make two changes in current code to make it working:
angular.module('cakethursdayApp', ['firebase'])
.service('FacebookAuthService', function FacebookAuthService($firebaseAuth) {
......
});
Inject AngularFire module as dependency
Replace $firebaseSimpleLogin with $firebaseAuth because
$firebaseSimpleLogin was dropped/removed in of 0.9.0.
