I have to use Edge at work. If those vertical tabs are coming, I'd certainly welcome it. I wish I could get vertical tabs that are actually drawn like a tree though: Like with the box drawing characters and indentation. The best feature in Firefox is container tabs - and there are a ton of uses outside of first party isolation. Chrome-based browsers need that.
