I'm going to lower my rating even though I still think this add-on is crucial and fantastic. But the fact that you still, after many years, haven't added the option to manually add a url to always open in a certain container is ridiculous. You should know how chaotic and irratic the devs of Google and Microsoft are today using 20 different domains just to be able to sign in somewhere. It's like they all suffer from DID. It's a hassle to use containers because of this, since you so often are thrown out of the container. Fix it!
