Microsoft Edge (Chromium) Extensions
Extensions are small programs that can be used to add new features to Microsoft Edge (Chromium) or modify the existing functionality. Extensions are intended to improve a user’s day-to-day browsing experience by providing niche functionality that is important to targeted audiences.
There is now just one programming model associated with building extensions for the Microsoft Edge (Chromium) browser and the Google Chrome browser. The model is based upon the open source Chromium engine now so all API calls and results will be identical. You are able to submit the same source code bundle to both the Microsoft and Google extension stores, making life easy now when it is time to publish your Extension.
