"Cookie Keep List" Rated 5 out of 5 stars

Thank you for a tool to create a "Cookie Keep List", something that 'standard' Firefox does not provide. Whilst Firefox Cookie Exceptions provides a method to Block or Allow or Allow For Session, it does not provide the ability to keep cookies already accepted, and this add-on does just that. It could be further enhanced if it deleted the unwanted cookies either when closing Firefox or at timed intervals.
