With Firefox Multi-Account Containers I am able to contain cookies to specific containers. I can then individually clear storage and cookies for each container. Sometimes I accidentally use an uncontainered tab. I have not found a way to clear uncontainered cookies and storage and not from my containers, as Clear browsing data and cookies clears it from everything. How can only clear everything not in a container? Please add a button which does this to Firefox Multi-Account Containers. I would also like to see which container items in history are from. Currently clearing cookies and storage data from containers doesn't remove the items from history. I can imagine this is because if they are not separate, it would remove occurrences where they were opened uncontainered or in different containers.
