🧹 TW Cookie & Browser Cleaner – with Whitelist & Per‑Domain Tracking Protection

Version 9.6.2 – For Chrome, Firefox and other Chromium browsers



📌 Overview

TW Cookie & Browser Cleaner is a browser extension that deletes cookies, cache, history, local storage and other browser data in a targeted way – without losing important logins.

A whitelist protects selected domains from deletion. Additionally, tracking protection can be activated per domain: only login‑relevant cookies are kept, all others (tracking cookies) are deleted.



✨ Main Features

• 🧹 Cleaning of cookies, cache, history, IndexedDB, LocalStorage, service workers, form data, download list and passwords (the latter only after confirmation).
• 🛡️ Whitelist – domains that will never be deleted (cookies and other data remain).
• 🔒 Per‑domain tracking protection – on whitelisted domains you can choose:
• "Keep only login cookies" → all other cookies are deleted.
• "Keep all cookies" → tracking is allowed.
• 🌍 Two languages – German and English (browser language is auto‑detected).
• 🔁 Automatic cleaning – on browser start, on browser shutdown or when a tab is closed (optional).
• 💾 Backup & restore – export/import of all settings (whitelist, tracking settings, data types) as a JSON file.
• 📝 Bulk editor – edit the whitelist as plain text and apply with one click.
• 🍪 Cookie inspector – view and copy all cookies of the current domain.
• 🐛 Developer mode (hidden) – accessible via devtools.html, disables automatic tab closing and enables debug logs.
• 🔥 Firefox compatible – unsupported data types (e.g. WebSQL, Plugin Data) are automatically disabled and hidden.

[9.6.1] - 2026-05-30

🚀 New Features / Verbesserungen

• Whitelist now starts empty – Preset domains have been completely removed.
  Users must add their own domains (initial defaults can be configured via tw-cookie-browser-cleaner-default.json).
• Hidden developer tools – Added devtools.html with:
• Developer mode (prevents automatic closing of options/privacy pages when the popup opens)
• Debug mode (writes detailed logs to console and storage)
• Debug log viewer and statistics reset
• Dynamic data type counting in Firefox – The popup now only counts actually visible data‑type checkboxes, fixing the “Cookies & 10 selected” issue.
• Centralised cookie count in popup footer – Shows all cookies in the browser, with dynamic colours:
• Green (<100), Orange (100–500), Red (>500)
• Improved UI – Reduced row heights in tables, accordion headers, and cookie inspector; unified font sizes.
• Default language set to English – Fallback to English for unknown browser languages (French, Spanish, etc. now see English instead of German).
• Backup filename changed – Now tw-cookie-browser-cleaner-backup-YYYY-MM-DDTHH_MM_SS.json.
• Removed “Reset all settings” row from popup – This rarely used action is now only available in the Options page.
• CSS Schriftgrößen-Fix – Ensures the last paragraph in info containers has a consistent font size (12px) on all browsers.
