CookieMop — Auto Delete Cookies on Tab Close

Automatically deletes cookies & site data when you close a tab. Keep only the sites you trust. Local, open-source, no tracking.

Looking for a Cookie AutoDelete replacement that works with Manifest V3? CookieMop automatically deletes cookies and site data the moment you close a tab — except for the sites you whitelist. No cleanup day, no buttons to press. It just happens. HOW IT WORKS 1. Browse anywhere — CookieMop watches which sites each tab visits. 2. Close the tab — after a short delay (15 seconds by default, configurable 0–60), if no other open tab uses that site, its cookies are wiped automatically. 3. Whitelisted sites keep you logged in, always. FEATURES • Auto delete cookies on tab close — the core of every good cookie cleaner, running quietly in the background • Whitelist: sites that are never cleaned (email, banking — stay logged in) • Greylist: sites cleaned only when the browser closes • Cleanup scope you control: cookies only, + localStorage, or + all site data (IndexedDB, CacheStorage, Service Workers) • Badge counter showing how many cookies the current site has set • Manual cleaning: "Clean this site now" and "Clean all except open tabs" • Local statistics: cookies cleaned today and in total • English & Korean UI PRIVACY PROMISE CookieMop is 100% local. No servers, no analytics, no accounts, no ads, no remote code — the extension makes zero network requests. It is fully open source; the store build is produced from the exact code on GitHub: https://github.com/thoopring/cookiemop COOKIEMOP PRO — OPTIONAL, ONE PAYMENT The core is free forever. Pro adds power-user extras — one payment, no subscription. • Rule profiles — keep one rule set for work and another for personal browsing, and switch with one click • Per-cookie whitelist — clean a site on every tab close while the cookie that holds your login survives $9.99 once. We have no servers, so we don't charge you monthly. Still zero network requests, even with Pro — your license is verified locally. There is no license server and no activation call, so Pro works offline and keeps working even if our payment infrastructure ever disappears. Your license key appears right after checkout, and you can look it up again any time with your email and order number — losing it costs you nothing. Nothing that was free has moved behind a payment, and nothing ever will be taken away from the free tier. SWITCHING FROM COOKIE AUTODELETE? Import your Cookie AutoDelete whitelist in one click: export your expressions as JSON in the old extension, then load the file in CookieMop's options page. Your whitelist and greylist convert automatically — the easiest cookie autodelete alternative migration you'll find. ROADMAP & SUPPORT Planned: wildcard domain rules, scheduled cleaning, cleanup history, settings export.
