What kind of settings? If you want per-site settings there is (was) uMatrix which allows for extremely granular configuration. Sadly it is discontinued right now. But it still works.
Let's say for example I'd like one container to have JavaScript disabled, and only enable the cookie autodelete add-ons. In another, enable JavaScript and some specific add-ons (like a password manager). Also, would be nice to be able to control cookie settings per container.
