title: Angular 8 Firebase Login with Google failing with previously working project
body: <p>I am working with a previously working Angular 8 project.  The Auth module is not working as expected.  When you click "login with google" the google account picker window pops up but then dissapears immediately.</p>
  
  <p>Basically 403: Requests to this API identitytoolkit method google.cloud.identitytoolkit.v1.ProjectConfigService.GetProjectConfig are blocked</p>
  
  <p>In the debug window I get the following error chunk:</p>
  
  <blockquote>
    <p>{"error":{"code":403,"message":"Requests to this API identitytoolkit
    method
    google.cloud.identitytoolkit.v1.ProjectConfigService.GetProjectConfig
    are blocked.","errors":[{"message":"Requests to this API
    identitytoolkit method
    google.cloud.identitytoolkit.v1.ProjectConfigService.GetProjectConfig
    are
    blocked.","domain":"global","reason":"forbidden"}],"status":"PERMISSION_DENIED"}</p>
  </blockquote>
  
  <p>}</p>
  
  <p>I have tried this on a couple of enviornements and it is still happening.</p>
