Microsoft Edge (Chromium) allows the installation of extensions but to install browser extensions in Edge, you have to visit the Windows Store. There can be instances where you might want to install extensions not from Windows Store but elsewhere. Edge browser supports this capability.
Also, if you are a developer and would like to test new extensions you’ll have to sideload Edge browser extension from outside the Windows Store. However, you’ll be required to enable extension developer features. Microsoft Edge allows sideloading (installation and running unverified extensions). Microsoft WebDriver supports the automated side loading of extensions in Microsoft Edge sessions. WebDriver is a platform and language-neutral interface that enables developers to create automated tests.
