Please add this. It really doesn't need to be complicated. It's just a special bookmarks folder that tracks read/unread state and defaults to reading view when opening items.
I love tab groups, they are such a great way of keeping all of my different hobbies, study areas etc separated. I couldn't live without them.The one thing that's painfully missing for me is syncing. iOS/iPadOS Firefox currently don't have tab groups ...
