I also would greatly appreciate this as tab groups are a vital part of my day-to-day life in web browsing. I use iOS so I can’t turn on the beta features. This being actually added would be vastly helpful.
I don't understand why they haven't implemented one of the most basic features available in most browsers. This is everyone thinks Firefox is inferior.
We searched for peace, we noble lads, A break from pop-ups, and autoplaying ads. But now we drown in mismatched slabs— Firefox, why won't you let us group our tabs?
