to the creator of Ad-Block plus:
This story from the Windows Central site came out yesterday:
titled "Microsoft is building a Chromium-powered web browser that will replace Edge on Windows 10"
https://www.windowscentral.com/microsoft-building-chromium-powered-web-browser-windows-10
it looks like Microsoft is giving up on its MS Edge browser in favor of making a Chromium-based browser in future releases of Windows 10
I'm not sure if development of Ad-block Plus for Edge will continue as Microsoft plans to phase out Edge
