Microsoft is released Chromium-Based MS Edge on 01/15/2020
This browser can use ChromeStore Extensions.
Correct.
That doesn't make it good, though. But it does make it possible that my experimental HTML5 game (which rendered properly in Gecko, WebKit, and Blink) will now work in MS's browser.
I'd filed a bug report (or something like that) for Trident-based Edge a couple years ago, since it was having a lot of difficulty with SVG's constrained by CSS styles of containing flexboxes. They never did fix that in Trident.
Also it's a shame we're basically down to two 'mainstream' rendering engines (technically maybe three, but I have found Blink and Webkit to be essentially the same functionally, especially now that Blink supports APNG).
