First, they are color coded / icon specific tabs, not full windows like chrome. I have used it a lot in the past when I'm doing sso testing at work, or logging into 5 or 6 different AWS accounts at the same time. It's really nice to jump from the green tab (Dev) to the red tab (prod) to check some settings or logs. They feel a lot lighter then full on chrome profiles. You can also tie each to specific proxy profiles, so in my last setup we used ssh tunnels to access different environments, so each container connected to different ssh tunnels.
