It used to be that Firefox had different containers. I kept separate ones for shopping, banking, Facebook, etc. Now I had to erase my MacBook Pro IOS, and after a few days of trying to use Safari, I installed Firefox. But I can no longer see the possibility of using containers. I found them particuarly helpful when I had more than one account for a certain platform - with containers, I didn't need to sign out and sign in to switch users. It also (supposedly) kept Facebook from tracking our interests. Has Firefox done away with containers? Or have I simply forgotten what they are called (buckets, maybe?). I searched and searched the help articles to no avail. If they have done away with them, why?

By the way, Chrome (which I had to use at work) started offering a similar product and it was also very helpful.
