Tab Cleaner

A Chrome / Chromium browser extension that automatically wipes your browsing data every time you close a tab — cookies, cache, history, site storage, permissions, and more.

---

Features

• Auto-clears on every tab close — no manual action needed
• Tracks what it removes — live bar chart showing cookies and history items cleared per session
• Wipes everything Chrome stores on you:
  • Cookies & site data
  • Cached images & files
  • Cache storage (PWA / service worker cache)
  • Browsing history
  • Autofill form data
  • Local storage
  • IndexedDB databases
  • Service workers
  • File system data
  • Download history
  • Site permissions (camera, microphone, notifications, geolocation, and more)
• Three clearing modes:
  • Every tab close (default)
  • Site data only — clears only the site you just closed
  • On last tab close — waits until all tabs are gone
• History time range — choose how far back history is cleared; cookies and cache always do a full wipe regardless
• Stats dashboard — see total cookies removed, total history removed, clears today, and time of last clear

Notes

• Passwords are off by default. Enabling them permanently removes all passwords saved in Chrome. Only turn this on if you know what you're doing.
• Web SQL is off by default. It was removed from Chrome 119+ and will silently be skipped if unsupported.
• The extension gracefully skips any data type that your browser version does not support — it will never throw an error and stop the clear mid-way.
• Stats are stored locally in chrome.storage.local and never leave your device.
