They updated the imports with v9. The fix is easy, just update to:

import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';

Here's the relevant section of the docs

I think this will work, even I faced the same problem Update imports to v9 compat

import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/database';

firebase.initializeApp(firebaseConfig);

const auth = firebase.auth();
const database = firebase.database();

Before: version 8

import firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/firestore';

After: version 9 compat v9 compat packages are API compatible with v8 code

import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';

For firebase v10 (it can work for other versions) use the following code: (worked for me)

import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';

firebase.initializeApp(firebaseConfig);

const auth = firebase.default.auth();
const database = firebase.default.database();
