Never click 'Reject All' again.
CookieKiller auto-rejects cookie consent popups on every website you visit. Zero tracking. Zero data collection. Just peace and quiet.
Reject-first, always.
Not a blocker that hides banners by accepting everything. CookieKiller actively clicks reject — the right way.

Common questions.
Does CookieKiller accept or reject cookies?
CookieKiller always rejects non-essential cookies. It clicks "Reject All," "Only Necessary," or equivalent. It never accepts tracking cookies.
Is my data safe?
Zero data collected. No browsing history, no personal info, no analytics. Only your popup counter and whitelist are stored — 100% locally.
Will it break any websites?
CookieKiller only touches cookie consent banners, never modifying page content. If a site needs cookies, whitelist it with one click.
How is this different from "I don't care about cookies"?
That extension was acquired by Avast (ad-tech) and often accepts cookies — harming your privacy. CookieKiller is independent, open-source, and always rejects.
Does it work outside of Europe?
Yes. Cookie banners appear worldwide due to GDPR, CCPA, LGPD, POPIA and similar laws.
Is it really free?
Completely free. No premium tier, no ads, no catches. MIT licensed. Privacy tools should be accessible to everyone.
