Enhancing the login/signup page using Firebase integration

**Description**

This enhancement aims to streamline the user login and signup process on our website by integrating Firebase Google Authentication. By implementing Firebase, users will enjoy a seamless experience, as they can log in or sign up with their existing Google accounts with just a few clicks. This not only simplifies the authentication process but also enhances security by leveraging Google's robust authentication mechanisms. Integrating Firebase into the login and signup pages will contribute to an improved user experience, reducing friction and increasing user engagement. Let's make this platform easier and more secure for our users by implementing Firebase Google Authentication.
