You could try one of the container management addons that simply spawn new containers as needed, e.g. containers on demand[0]. In principle the underlzing building blocks for containers and private browsing are orthogonal that can be used at the same time, i.e. a container in private browsing mode is yet another context that will have private browsing features (nothing written to disk) but is also separate from other private browsing tabs. But I'm not sure if that this is exposed through UI or APIs. [0] https://addons.mozilla.org/en-US/firefox/addon/containers-on-the-go/ https://addons.mozilla.org/en-US/firefox/addon/containers-on...
