Rated 5 out of 5 stars

Works just fine, the concept here deployed concerning cookies management is the only one I agree with, and this extension is the only one I know that performs this exact way.
One thing I think is necessary to point out/remind is that, if within this extension the option 'Automatically remove cookies as per preference when Firefox is closed' is chosen, this option will only succeed if within Firefox's Options/Privacy/Settings, 'Cookies' is unchecked, because otherwise ALL cookies will be removed when Firefox is closed.
