Edge has had vertical tabs with tab groups natively for a couple years now. It also has a nice Reader mode, good text-to-speech, and a screenshot tool built in. And it supports uBlock Origin as an add on.
Yeah, that's not the same, or even functionally close. Just a superficial resemblance. The value of tree style tabs is that you don't manually organize anything, and the tabs are nested arbitrarily deep so that you literally end up with a hierarchical tree of tabs that shows you the logical view of your browsing history with no manual input on your part. (Note the comparison to edge has been made before, which is why I specifically said tree-style tabs, not vertical tabs.)
