Cookies are small pieces of digital data that I place on your computer through your web browser. They allow me to remember you when you revisit my website and make the site more relevant to your interests.
Most browsers will tell you how to adjust my cookies settings in the Help menu. This will let you configure how your browser deals with requests from websites to store cookies. You can stop accepting new cookies, ask to be notified of new cookies you receive or disable cookies completely. Similar changes can be made for browser add-ons from the settings for the add-on or failing that, consult the developer's website.
