> I can't figure out how to turn off that built in one I don't see the facebook container to be built-in. I have only the multi-account container extension installed, and I can make any website to open by default in the container I have created for facebook. I think, you will have to uninstall/disable the facebook-container extension, and just have the multi-account container extension enabled.
