Microsoft has shipped the first preview release of Microsoft Edge with extensions support to Windows Insiders.
Since the beginning of the Microsoft Edge project, the roadmap has always included extensions in order to support a community of developer innovation on top of the browser, enabling new and interesting scenarios for customers. The highest priorities remains to ensure that Microsoft Edge is the safest, most reliable and fastest browser. Experiences have taught us all that poorly written or even malicious add-ons were a huge source of security, reliability and performance issues for browsers.
With this in mind, Microsoft has built Edge so customers can add extensions to the browser with the confidence that they will operate as expected.
To ensure the highest quality experience for customers, and as Microsoft has done with Windows 10 since the beginning, they will introduce extensions first to the Windows Insiders and then roll them out more broadly to all Windows 10 users. Initially the Insiders will download and then sideload extensions for testing purposes, but ultimately the extensions will be available to all users via the Windows Store to ensure the quality of the end-to-end experience.
The Windows Insider build will include three preview extensions: Microsoft Translator, an extension that automatically translates pages in over 50 different languages, a Mouse Gestures extension, and an early preview version of the popular Reddit Enhancement Suite (RES). Later this year customers will find popular extensions from partners like AdBlock, Adblock Plus, Amazon, LastPass, Evernote and more.
