4 export is only valid in modules. Modules are imported with <script type="module">. – Sebastian Simon Commented Sep 11, 2021 at 6:49

The v9 SDKs are shipped as JavaScript modules by default. To use them in a regular JavaScript import, and to use your style of code, you can instead import the compatibility layer as shown in the documentation on using the compat library from your window:

<script src="https://www.gstatic.com/firebasejs/9.0.2/firebase-app-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.0.2/firebase-firestore-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.0.2/firebase-auth-compat.js"></script>
