That’s a pretty emphatic statement. I use Firefox’s Tab containers extensively and haven’t found a good analog in chromium based browsers. Can you recommend an extension or addon that provides this functionality?

The API for this should come up in next few months. Besides cookies/storage/other state mediums can be compartmentalized even now atleast theoretically with an extension.

The colored tab border isn't possible yet in chromium, and there's hope that the API will come up for this.
