CookieMaster od Craig Miskell

In a similar style to the old pre-WebExtensions CookieMonster plugin, CookieMaster allows you to control which sites are allowed to set cookies, focusing mainly on first party cookies.

By default it blocks all 3rd party, but you can be specific about them as well if you want, allowing your choices, and denying all the rest.

Privacy: Does not collect/share any information with the Developer or any 3rd parties. May or may not prevent information (cookie) transfer to/from sites you are visiting, as controlled by your local configuration.
