I use Firefox but refuse to recommend it until tab groups become a thing. edit: i have tried a few tab group extensions and find that they all have some kind of fatal flaw that stops me from being able to use them as a good substitute for chome's option. the best substitute for me is currently multi account containers, although I don't like how long it takes to switch between containers and that the tabs have to reload whenever the containers are shown.

There's multiple extensions to do that, not sure how good any are, though
