This is honestly a killer feature! I use Temporary Containers and load the AWS console in a fresh container automatically, making it very easy to switch between accounts and have multiple open at once. (Caveat emptor: be sure which account you're using at any given time!)

It really is. I think this is one of the features they (Mozilla) spend some more resources into. It's really unique and could drive non-tech savvy users to it.
