[Shadowed_]

I don't care much about vertical tabs but what I want from tabs is automatic grouping by site. I'm surprised nobody made this. I know there are extension supporting grouping but i have never seen any that automatically groups by website.

It's probably not helpful to you since it's a different browser, but Safari has this. Right click on any tab in its vertical tabs list and choose Arrange Tabs By -> Website.
