Quote:Microsoft revealed plans to switch the core of the company's Microsoft Edge web browser from its own EdgeHTML base to Chromium used by Google Chrome, Opera, Vivaldi, Brave, and other browsers.

First preview versions of the "new" Microsoft Edge browser will become available in early 2019. Microsoft launched an Insider program for Edge that anyone can sign-up for to gain access to these early builds.

The move offers advantages: Edge will support all supported versions of Windows and not just Windows 10, a version for Mac OS X and other desktop operating systems is likely, and Edge updates won't be linked to Windows updates anymore.

Some things were not clear when Microsoft made the initial announcement:

• Would Microsoft switch from EdgeHTML to Chromium for UWP applications?
  
• Would Microsoft Edge support Chromium extensions?
  

Microsoft Edge project manager Kyle Alden responded to questions about the move on Reddit. He stated that it was Microsoft's "intention to support existing Chrome extensions". Whether that means that existing extensions for Microsoft Edge won't be supported anymore by the new Edge browser is unknown.
