Bookmark Data Cleaner — One-click cleanup for bookmark removals

🏆 Attracting ~120 users on the Chrome Web Store with a 5-star rating

A Chrome extension that clears related browsing data when you delete a bookmark—so you remove the site and its leftover storage in one sweep. It supports cache, cookies, file-system data, IndexedDB, localStorage, plugin data, and WebSQL, with a simple flow designed to be fast and predictable.

Why it Matters#

Over time, bookmarks turn into “dead weight,” and the sites they point to can leave behind megabytes of storage and tracking artifacts. Cleaning that by hand is slow and error-prone. Bookmark Data Cleaner gives you a focused safety valve: when you prune a bookmark, you can also clear the associated site data—freeing space, reducing fingerprinting surface, and keeping your browser tidy.

Key Highlights#

  • One-sweep cleanup: remove a bookmark and clear its related browsing data in the same action.
  • Broad data coverage: cache, cookies, file-system data, IndexedDB, localStorage, plugin data, and WebSQL.
  • Lightweight & focused: small footprint; built purely for bookmark-adjacent cleanup.
  • Published on Chrome Web Store: v2.2, last updated April 18, 2023; shows a 5.0 rating (2 reviews) and ~120 users at the time of writing.

Technical Foundation#

  • Platform: Chrome Extension (Manifest-based)
  • APIs: browsingData for scoped data removal; bookmarks integration for the delete flow. (As implied by the feature set.)
  • Languages: HTML, JavaScript, CSS (repo breakdown).
