Impossible to use Firebase React with Manifest v3

[ctjlewis]

Summary

It is not possible to use Firebase React in Chrome extension content scripts using manifest v3 because the CSP settings that Firebase requires to work are prohibited by Chrome's new CSP policies. Since it is no longer possible to publish new MV2 extensions, new extensions are unable to use Firebase in their documents (e.g. popup window).

Original post

I have had the unique pleasure of trying to package a Firebase-enabled application as a Chrome extension, only to find that with manifest v3 the only way to do this is in a service worker, which comes with great limitations on how users can authorize with Firebase Auth and so on.

It is important that Google's own Chrome Extensions ecosystem is compatible with Google's own Firebase software, but I am not shocked to see the attempt to force developers to break their own apps before January 2022 when this team intends to deprecate manifest v2 even though this will preclude future extensions from integrating Google's own technology.

Peep the comments of this video for some examples of how distraught developers are about this issue, and plenty similar posts exist on StackOverflow as well:

What do?

Specifically, https://firebaseopensource.com/projects/firebase/quickstart-js/auth/chromextension/readme/ does no longer work in MV3, in this case not because serviceworker restrictions per se, but because the extension has no rights to open a popup window. Would it be better to open a new issue for that ?

Does anyone know this problem will be solved?

Is there really no guidance on using Firebase Auth in a Chrome extension with mv3 now? CWS has already disallowed new v2 submissions; are we to just suspend development?

Thought I suspect most know this and doesn't solve for the popup problem, perhaps this is useful for others searching.
Firebase Auth works from a manifest v3 service worker using signInWithCredential:

1. Use chrome.identity.getAuthToken() to retrieve the auth token for the user.
2. Generate a credential via GoogleAuthProvider.credential().
3. Pass that credential to signInWithCredential().

Thanks for the help!
Before adding the sign in feature, I will need to add fireabase to the extension.
Can you please let me know how did you connect firebase to mv3 chrome extension? I checked a lot of websites online, but majority of them are in mv2 & if found in mv3, they are faulty ones.
Can you please let me know how did you make the connection?

Hey , did by any chance find a solution to add firebase in V3

Not yet

As I pointed out in the OP, it is not possible to use Firebase at all in a Manifest v3 extension because the CSP policies that Firebase requires are prohibited by the CSP policies that control Chrome extensions in v3. It cannot be done without updating the library's logic itself.

I use it. What features are you trying to use? I use auth, firestore, and functions. Here's an implementation of the general idea that I proposed above:

// in the service worker

import { initializeApp } from 'firebase/app';
import { getAuth, GoogleAuthProvider, signInWithCredential, User } from 'firebase/auth';
import { getFirestore } from 'firebase/firestore';
import { getFunctions } from 'firebase/functions';

const firebaseConfig = {
  // your config
};

const app = initializeApp(firebaseConfig);
const auth = getAuth(app);
const db = getFirestore(app);
const functions = getFunctions(app);

const getGoogleAuthCredential = () => {
  return new Promise<ReturnType<typeof GoogleAuthProvider.credential>>((resolve, reject) => {
    chrome.identity.getAuthToken({ interactive: true }, token => {
      if (chrome.runtime.lastError) {
        console.error(chrome.runtime.lastError);
        reject(chrome.runtime.lastError);
      }
      const credential = GoogleAuthProvider.credential(null, token);
      resolve(credential);
    });
  });
};

const signIn = async () => {
  try {
    const credential = await getGoogleAuthCredential();
    const result = await signInWithCredential(auth, credential);
    return result.user;
  } catch (e) {
    console.error(e);
    return null;
  }
};

This requires the indentity permission in manifest.json, e.g.:

{
  "manifest_version": 3,
  "permissions": [ "identity" ]
}

how did you make the connection?

Do all communications from the service worker and then pass messages with your data between that and content, popup, devtools, etc.

@ibejoeb

Can you please make a repository having firebase connections with google authentication?(in mv3)

Your repo would be very helpful to use as a starter template for our projects

This is not possible because there is no way to allow external hosts in the CSP with V3. What may work is using chrome.identity API (stackoverflow) with firebase auth which won't invoke any firebase popups or redirects which are no longer possible in MV3.

[ibejoeb]

This is documented. It may not have been when this issue was opened, but it is now acknowledged that certain auth features are not available:

from https://firebase.google.com/docs/web/environments-js-sdk#auth-note:

All Authentication features, except phone authentication and popup/redirect OAuth operations, are supported.

There are limitations on using Auth. But it is not "Impossible to use Firebase with Manifest v3."

[ctjlewis]

@ibejoeb - I was specifically referring to Firebase React in a popup window. I edited to clarify.

[Atharv777]

One temporary fix is that we can make an API on firebase functions. Is there any other workaround for it?

[MakingStan]

Is this solved?

[ghost]

How can I use signInWithPhoneNumber in chrome extension react?

[mohanish2504]

using chrome.identity will prohibit us from using it in Microsoft edge extension.

[fablorv]

any updates anywhere on using firebase with MV3 ?

[dbjpanda]

Any updates or workaround on the issue except using chrome.identity?

I used code above from @ibejoeb with this boilerplate
https://github.com/guocaoyi/create-chrome-ext/tree/main:

// Import the functions you need from the SDKs you need
import { initializeApp } from 'firebase/app'
import {
  getAuth,
  signInWithPopup,
  GoogleAuthProvider,
  signInWithRedirect,
  signInWithCredential,
} from 'firebase/auth'
// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries

// Your web app's Firebase configuration
// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
///...
}

// Initialize Firebase
const app = initializeApp(firebaseConfig)
const auth = getAuth(app)

const getGoogleAuthCredential = () => {
  return new Promise<ReturnType<typeof GoogleAuthProvider.credential>>((resolve, reject) => {
    chrome.identity.getAuthToken({ interactive: true }, (token) => {
      if (chrome.runtime.lastError) {
        console.error(chrome.runtime.lastError)
        reject(chrome.runtime.lastError)
      }
      const credential = GoogleAuthProvider.credential(null, token)
      resolve(credential)
    })
  })
}

const signIn = async () => {
  try {
    const credential = await getGoogleAuthCredential()
    const result = await signInWithCredential(auth, credential)
    return result.user
  } catch (e) {
    console.error(e)
    return null
  }
}

;(async () => {
  debugger
  console.log('users', await signIn())
})()

chrome.runtime.onMessage.addListener((request) => {
  if (request.type === 'COUNT') {
    console.log('background has received a message from popup, and count is ', request?.count)
  }
})

Make sure that you have uploaded your extension to store and a key property:

"oauth2": {
    "client_id": "YOUR_EXTENSION_OAUTH_ID.apps.googleusercontent.com",


    "scopes": [
      "https://www.googleapis.com/auth/userinfo.email",
      "https://www.googleapis.com/auth/userinfo.profile"
    ]
  },
"key":"ThisKeyIsGoingToBeVeryLong/go8GGC2u3UD9WI3MkmBgyiDPP2OreImEQhPvwpliioUMJmERZK3zPAx72z8MDvGp7Fx7ZlzuZpL4yyp4zXBI+MUhFGoqEh32oYnm4qkS4JpjWva5Ktn4YpAWxd4pSCVs8I4MZms20+yx5OlnlmWQEwQiiIwPPwG1e1jRw0Ak5duPpE3uysVGZXkGhC5FyOFM+oVXwc1kMqrrKnQiMJ3lgh59LjkX4z1cDNX3MomyUMJ+I+DaWC2VdHggB74BNANSd+zkPQeNKg3o7FetlDJya1bk8ofdNBARxHFMBtMXu/ONfCT3Q2kCY9gZDRktmNRiHG/1cXhkIcN1RWrbsCkwIDAQAB" 

Alos create a OAuth 2.0 Cliend ID for chrome extension:

After that allow firebase google auth interact with other client:

Worked for me:
