Answer 1

I strongly suspect you didn't follow all the setup instructions completely. Be sure to go back and follow them all, especially part 2: Register your app where you create an app in the console to associate your web app with its configuration.

If you've followed all the instructions exactly, please contact Firebase support directly for troubleshooting assistance.
