firefox: clear granted containers upon closing browser

[dannysteenman]

It's possible to clear the granted containers via the plugin manually by clicking the clear container button. would it be possible to clear the containers automatically when I close the browser, similar to clearing cookies?

the reason for this is over time I accumulate lots of containers over the diferent accounts that I access and sometimes there are strange issues popping up (network errors) in the aws console when clicking through the console and trying to access resources. Normally this is solved when clearing the containers and restarting the session hence this request.
