Firefox containers are tab groups on steroids. Tab groups are just aesthetic while Firefox containers can not only group and colour code the tabs but isolate cache and stuff. This means you can use two gmail accounts in two separate tabs. It also means you can isolate you personal bank or other websites so that other data harvesting website cant get to that information. :)
Firefox containers have been there long back before tab groupings were available in Chrome as well.
