Too many web sites (e.g., New York Times, New Yorker, Google) do not honor the request to block tracking cookies. They add them back in within seconds after I delete them. Most of the added cookies are not, repeat not, from the owner of the website but are added via some agreement with the site owner. Most of these cookies are from sites having no connection with me or the site provider. Can or will Firefox provide an option to block all cookies inserted from the web site?
