Local storage token Problems - javascript

So this problem I am facing for quite some time. Basically Registering user work to some extent. This is what is happening, upon the user being created and me getting the Auth token displayed in the dev-tools/Application and me being pushed to the home as I should.
When I refresh the page I get this error × Error: A cross-origin error was thrown. React doesn't have access to the actual error object in development. See https://reactjs.org/link/crossorigin-error for more information. I can fix this by clearing the localStorage. So if every time a new user is created, and if it wants to refresh the page, I will have to clear local storage every time. Which is totally not convenient.
There is another error, The logout handler is bugging, when I press the logout button it is displaying this error TypeError: Cannot read property 'push' of undefined and it pointing out the error is located in the UserContext. I would really appreciate some help really.

}catch(error){
disptach({
type:REGISTER_USER_FAIL,
payload : error.response.data.message
})
}
}
The register form is as follow..
import React, { useState, useEffect } from "react";
import { Link, useNavigate } from "react-router-dom"
import { useSelector, useDispatch } from "react-redux"
import Loader from "./loader";
import { Register } from "../actions/UserAction";

After you login, you have only set the authToken into your localStorage and not in your Provider. You'll need to call setUser after you login in order for Header component to know user is logged in.

TypeError: _fire__WEBPACK_IMPORTED_MODULE_11__.default.collection is not a function

I have a project where I'm using Firebase for the backend and ReactJS as the front end. I have successfully implemented the authentication and it's up and running but I can't seem to make my Firestore work. here is my fire.js file:
import firebase from 'firebase';
import "firebase/auth";
import "firebase/firestore";
if (!firebase.apps.length) {
var fire = firebase.initializeApp({
// my credentials //
});
}else {
fire = firebase.app(); // if already initialized, use that one
}
//const fire = firebase.initializeApp(firebaseConfig);
export default fire;

//import AddRecord from './AddRecord';
import * as FaIcons from "react-icons/fa";
import * as AiIcons from "react-icons/ai";
import { SidebarData } from './SidebarData';
//import { AddRecord } from './components/AddRecord';
import { IconContext } from 'react-icons';
import Button from 'react-bootstrap/Button';
import fire from "../fire";
const ContactUs = () => {
const [sidebar, setSidebar] = useState (false)
const showSidebar = () => setSidebar(!sidebar)
//const Hero handleLogout={handleLogout};
const [name, setName] = useState("");
const [email, setEmail] = useState("");
const [message, setMessage] = useState("");
const handleSubmit = (e) => {
e.preventDefault();
fire.collection('contact').add({
name: name,
email: email,

})
.then(() => {
alert("Thanks! We'll get back to you soon!");
})
.catch(error => {
alert(error.message);
})
setName("");
setEmail("");
setMessage("");
};

export default ContactUs;
Your fire variable is the result of initializeApp, which is of type App. You need to call the firestore method to access the Firestore Service Interface:
fire.firestore().collection('contact')...
