How to disconnect from google authentication after angularfire2 / auth signOut?

Question

I am building a website using Angular and Firebase. I use the Angularfire2 and AngularFireAuth and GoogleAuthProvider (Google) libraries as my authentication provider.

Here is my service code:

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { AngularFireAuth } from 'angularfire2/auth';
import * as firebase from 'firebase/app';

@Injectable()
export class AuthenticationService {
  user: Observable<firebase.User>;

  constructor(public afAuth: AngularFireAuth) {
    this.user = afAuth.authState;
  }

  login() {
    this.afAuth.auth.signInWithPopup(new firebase.auth.GoogleAuthProvider());
  }

  logout() {
    this.afAuth.auth.signOut();
  }
}

When a user "logs out" of my site, he works, but it seems to "cache" Google authentication. Therefore, when they try to log in a second time, I encounter several problems:

• The user is not allowed to choose a different Google account to log in.
• The user automatically logs in ... which seems like a security issue. Another user can go to the same shared PC and log in as the previous user and no password is required for this.

.when('/logout', {

logout.html:

<div class="container" >

<iframe id="logoutframe" src="https://accounts.google.com/logout" style="display: none"></iframe>
