};
firebase.initializeApp(config);

Recently even i faced the same error.

You are opening this file directly in the browser without any webserver. Firebase authentication work if you open file directly. Try to load your html through webserver it should solve your issue. The reason behind this bug is when you use authentication services they will use web storage. web storage not works when you open a html file directly without any web browser

For example use use apache and open through apache like http://localhost/filename.html in browser

Try this code. It should work.

    var config = {
    apiKey: "*****",
    authDomain: "******",
    };
    firebase.initializeApp(config);
    var provider = new firebase.auth.GoogleAuthProvider();
    provider.addScope('profile');
    provider.addScope('https://www.googleapis.com/auth/drive');
    firebase.auth().signInWithRedirect(provider);
    //add the code below to your previous lines
    firebase.auth().getRedirectResult().then(function(authData) {
        console.log(authData);
    }).catch(function(error) {
        console.log(error);
    });
