Cookie Blocker by Privall

Cookie Blocker runs only in Firefox, on your device. It blocks cookies you do not allow, hides consent popups, and reduces common tracking. Nothing is sent to a server. Settings, your whitelist, and logs stay in Firefox on this device. Choose how cookies are blocked. Trackers blocks known advertising and analytics cookies. Third-party blocks cookies from sites other than the one in the address bar. All cookies blocks every cookie except first-party login cookies, unless you turn that option off. Domains you whitelist are not blocked. Whitelisting a domain means Cookie Blocker will not block cookies on that domain. Hide cookie notices hides consent popups and tries to reject them in English and Turkish. This is in beta and can miss an unknown notice.
Advanced Protection can clean tracking tags such as utm, fbclid, and gclid from links you open, shorten the referrer so other sites see only the site name, send a Global Privacy Control signal, block third-party requests to known ad and analytics servers, and limit WebRTC so a page is less able to learn your real network address. The site you are visiting still loads. You can turn each of these off in Settings. Blocked cookie names are kept in a local log. You can filter that log by cookie or site and clear it. Counts and logs never leave this browser. Cookie Blocker is developed for privacy, security, and educational purposes. It is provided as is. Illegal use of this extension is not our responsibility. You are responsible for how you use it and for following the laws that apply to you.
