title: Firebase google auth won't let me choose the account to connect with
body: <p>I have implemented Firebase Auth into my app to let my users connect with their Google accounts. So far so good, however once a user has chosen to connect with a specific account from the google account chooser popup, he won't be able to choose a different account the next time he logs in. The previously selected account will be automatically picked for the authentication.</p>
  
  <p>I really don't find this behavior correct, so I am trying to fix it.
  After some research I found that I can use <code>setCustomParameters(prompt: "select_account")</code> with the <code>googleProvider</code>, like so:</p>
  
  <pre><code>this.googleProvider = new firebase.auth.GoogleAuthProvider();
  this.googleProvider.setCustomParameters({
     prompt: "select_account",
  });
  </code></pre>

  <p>In my case, using the <code>consent</code> and <code>select_account</code> parameters don't seem to have any impact, the user does not get to choose which account to use.</p>
  
  <p>Edit: It would seem that it works correctly with chrome, but not with firefox...</p>
