Microsoft Edge is an incorporated browser present in the Windows 10 operating system. The company has voluntarily killed its Internet Explorer 11 to boost the user’s engagement with the new Microsoft Edge browser.

General Manager of Edge program, Drew DeBruyne has mentioned in Windows Experience Blog as follows,

To ensure the highest quality experience for customers, and as we have done with Windows 10 since the beginning, we will introduce extensions first to our Windows Insiders and then roll them out more broadly to all Windows 10 users. Initially our Insiders will download and then sideload extensions for testing purposes, but ultimately we will make extensions available to all of our customers via the Windows Store to ensure the quality of the end-to-end experience.
In the meanwhile, the company is strictly monitored in releasing extensions for the Microsoft Edge Browser. Poorly written or any other dangerous code might decrease the performance of the browser and also it might create security issues for the operating system.
