Firefox Multi-Account Containers are impossible to go back from once you get used to them. Add in Conex (https://addons.mozilla.org/en-US/firefox/addon/conex/) and you have really great tab group switching WITH containerization / "firewall" between containers.
You can't get anywhere near this with Chrome as far as I'm aware.
Far inferior IMO. Containers are incredibly lightweight compared to opening a separate profile. I would say Firefox profiles are more cumbersome to use than chromes..
I like profiles, use them all day long, but I wish there was a container-like way to isolate sub-profile tabs. Similar to the "facebook container" or being able to have multiple aws account sub-containers in my "work" profile. It's something I wish I could do.
