Feature Request for Temporary Cookies Rated 5 out of 5 stars

It's the best cookie manager for Firefox! But I miss one feature that would make it perfect: It would be awesome if Cookie Monster could automatically allow temporary cookies for specific sites when entering those site - and deleting all the cookies of a site when leaving it.

For example, I go to mail.google.com and login. Cookie Monster would automatically allow a temporary cookie which is necessary to log in to Googlemail. When logging out and leaving the page (closing tab or navigating away), Cookie Monster then would delete the cookies that have been set by mail.google.com. This would be useful, because many people also use Google search, but don't want a cookie for this, only for the subdomain mail.google.com.

This review is for a previous version of the add-on (0.97.0).
