Blocking cookies can be a smart move for several reasons: safeguarding your privacy, altering how your browser interacts with certain sites, or enhancing web development testing. Simply click "Block cookie" to get started, then select the parameters you wish to use to block the cookie.

If you leave the default settings of "Block with domain" and "Block with name" active, any cookies with both that domain and name will be automatically erased as soon as they're created. You can easily review and modify the list of blocked cookies by opening the extension's options and selecting "Blocked cookies."
