title: Transport Unavailable for OAuth
body: <p>I am trying to login with google into my firebase project and I am getting a transport unavailable error with both the popup and redirect functions from firebase. Is it because I am working locally or am I doing something wrong here?</p>
  
  <pre><code>var app = angular.module('WOM', ["firebase"]);
  app.controller('SampleCtrl', ['$scope', '$firebaseObject', '$firebaseAuth', function($scope, $firebaseObject, $firebaseAuth){
  var ref = new Firebase('https://who-owes-me.firebaseio.com/'); //Where data is stored
  var auth = $firebaseAuth(ref);
  
  $scope.login = function() {
      $scope.authData = null;
      $scope.error = null;
  
      auth.$authWithOAuthPopup("google").then(function(authData){
          $scope.authData = authData;
      }).catch(function(error){
          $scope.error = error;
      });
  }
  
  $scope.data = $firebaseObject(ref); //assign data to scope
  
  $scope.data.$loaded()
      .then(function(){
          console.log($scope.data);
      })
      .catch(function(err){
          console.error(err);
      })
  }]);
  </code></pre>
