Clearing cache and cookies in the container when closing Firefox

[qc0ekmlJS]

The “Clear cache and cookies when closing the browser” option is missing from the container settings.
Often there is a use case where you create a container for certain sites to track you less, and for such cases the option to automatically clear the cache is missing

Can you add a menu item “Clear cache and cookies when browser closes” in each container's settings?

This functionality seems like a no-brainer given the core focus of containers is privacy. I think it should actually be "Clear cache and cookies after closing the last tab in this container." We should not need to restart a whole browser session just to dump the cache and cookies for a given container.

Or is this not a Settings option because it is built-in behavior?

For example, I have a pattern on “https://www.google.com/search?q=” which opens a search tab in a new container without login to google, but for other google services I remain logged in (Gmail, Calendar) and for this container I would like to clear cookies and cache when closing the browser, because it is a temporary container for googling.
