As a Chinese user, it's really a painful process to install extensions for any chromium-based browsers except those made by Chinese companies. You know, Google services are totally blocked in mainland China (except downloading and updating of chrome, translate CN version, map CN version), however, chrome now requires all extensions being installed from Chrome web store. Developer mode will give a notification every time you start browser. Although an group policy template can solve the problem, you need to know the extension ID and find the link to download the group policy template. Then you have to use what we call "scientific way to surf the internet". So, Chinese users wil be very happy if Microsoft can hold a selected library of chrome extensions in Microsoft store. I'm certain this will make users of Edge grow rapidly in China.
