javascript - How to fix "This operation is not supported in the environment this application is running on. "location.protocol" ..." error?

Question

I try to use Firebase (Google) authentication but I'm getting this error:

This operation is not supported in the environment this application is running on. "location.protocol" must be http, https or chrome-extension and web storage must be enabled.

My code is:

var provider = new firebase.auth.GoogleAuthProvider();  

function Singin(){
  firebase.auth().signInWithPopup(provider).then(function(result) {
    var user = result.user;
    console.log(user);
  }).catch(function(error) {
    console.log(error);
    console.log(error.message)
  });
}

The full error is:

zi {code: "auth/operation-not-supported-in-this-environment", message: "This operation is not supported in the environment…chrome-extension and web storage must be enabled."}
code: "auth/operation-not-supported-in-this-environment"
message: "This operation is not supported in the environment this application is running on. "location.protocol" must be http, https or chrome-extension and web storage must be enabled."
__proto__: Error
