EditThisCookie for Chrome and Opera is a cookie management extension/add-on capable of adding, blocking, deleting, editing, searching, and protecting cookies.

This handy little extension/add-on was designed to help combat one of the causes of a sluggish machine: accumulated cookies. Websites you visit set cookies with expiration dates that can be a long way off. So, as you browse, more and more cookies are set and stored. EditThisCookie can be set up to automatically shorten the expiration dates of cookies, improving your browser's overall performance.

Below provides you with a few explanations of EditThisCookie usage.
