Answer 1

I had this error message when I had my browser popup-blocker enabled.

I disabled my popup blocker (I'm using Brave browser so I actually set it to 'Shields down for this site') and it worked for me.

I had the same problem with Firebase auth in dev mode. The problem is due to some incorrect cors setting in my local dev server.

Try go to networks on chrome and see if there is any cors-related error. If so, the solution is to remove any cors related setting on your local dev-server.
