Cookie expiration date
If websites do not set a date for persistent and third party cookies to expire, then this poses a threat to your privacy. Hence, set the maximum number of days within which a cookie has to expire. Once you configure this within the firewall, this expiration date will be applied to all cookies saved by websites on your computer.
