This is my very first Edge browser extension! It is a minimalist tool designed to test and verify basic extension loading and popup logic. When you click the icon on the top right toolbar of your browser, you will see a "Hello Edge" popup window. Although this project is simple, it covers the entire basic process of learning browser extension development. I learned how to write manifest.json, how to design the popup interface, and how to package the code and upload it to the Microsoft Store. This project does not collect any user data, and the code runs entirely locally. AI-assisted learning was used throughout the development process. It is perfect as a beginner's reference case. I hope everyone likes it!
