You do not want to use cookies when localstorage can do. That is because

• Cookies can be accessed/modified through background page only.
• Cookies are stored in context of a url/domain and not extension. So you will have to store a cookie for every domain that you wish to operate upon.
• With every HttpRequest all the cookies associated with corresponding url/domain gets transmitted to server, so in effect you will be adding overhead to user's requests.)
