The Price Tracker is a browser extension designed to allow users to select and track prices on various websites, receiving notifications when prices change. This document covers the basic framework setup of the extension.

To install the extension in Firefox:

• Open Firefox and navigate to about:debugging.
• Click on "This Firefox" (or "Load Temporary Add-on").
• Browse to the location of your extension files and select any file within the extension folder (usually the manifest.json).
• The extension should now appear in your browser's toolbar.

As of now, the extension includes:

• A basic user interface (popup) that opens when you click the extension icon. It contains a button and a brief instructional text.
• A background script (background.js) that runs as long as the browser is open. Currently, it logs a message to the console.
• A content script (content.js) that can interact with web pages. It is set up to log a message when executed.

Future updates will focus on implementing a CSS selector tool and functionality for tracking and notifying price changes on webpages.
