Hi @DeveloperKamlesh, did you set the correct environment variables in .env?
Here's the sample environment variables required to setup Firebase: https://github.com/hoppscotch/hoppscotch/blob/main/packages/hoppscotch-app/.env.example

If you're accessing the Firebase app from https://domain-name:3000, you have to add it to the Google Cloud Platform console > APIs & Services > Credentials > Browser Key.

I have set no restriction for any domain, so might be no need to add any domain name, Sir!

Since this is not an issue with Hoppscotch but rather it relates to Firebase you might want to raise this issue in Firebase JS SDK repository. Hence closing.
