You mean Chrome, since Microsoft Edge is based on that? Might as well call that a Chrome Distribution with a Microsoft UI, just like Brave, Opera, Vivaldi and other Chrome based browsers.
That pretty much confirms all my suspicions [0] as to who really has the upper 'Edge' of the web. It's really Chrome or WebKit. Firefox has no chance in competing against any of them since Chrome is where the ecosystem is (Electron, Web APIs, Latest features, etc)
Best part? Firefox is becoming irrelevant and Mozilla is kept on life support by Google as the world moves on.
