I actually tried Edge on Linux when it was in preview stage(because MS Teams wasn’t fully compatible with Firefox, all features didn’t work) and it started as a rather okayish fork of Chromium with features like vertical tabs integrated. Then it only got worse as additional features were piped in from top. It became bloated and a cursory glance at it’s right click menu just gives it all(which isn’t customizable in Edge but can be done in Firefox via userChrome.css file).
