If in any browser, when i am logged in with single google account and try to invoke \'sign in with google\' option on firebase, it is automatically logging-in to firebase wi
This worked for me: https://groups.google.com/forum/#!topic/firebase-talk/gxBm0WKCuIY
var provider = new firebase.auth.GoogleAuthProvider();
provider.setCustomParameters({
prompt: 'select_account'
});
If you're authenticating the user credential Using Google Sign-In with JavaScript, try to remove the follow line of code:
provider.addScope('https://www.googleapis.com/auth/plus.login');
After you clicked the sign in button, it will allow you to select a Google account that you want to use.
