Bookmark Cleaner: Fix Dead Links, Remove Duplicates

Bookmark Cleaner — make your bookmarks usable again 【Why you need it】 After a few years of collecting, bookmarks pile up: dead links, duplicates, and pages you forgot why you saved. Browser built-in tools are weak. This extension is a safe, thorough, fully local cleanup. 【Clean】 • Broken bookmark detection (404 / network errors / timeouts, auto-categorized with reasons) • Duplicate finder with URL normalization — ignores tracking parameters • Empty folder scan (nested included) • Handles large collections — engineered for 10,000+ bookmarks • Search, filter and sort every result before you delete anything 【Safe】 • Everything goes to a local recycle bin — restore anytime • One-click full backup (JSON, re-importable) • Operation history with step-by-step undo (archive / move / rename) 【Organize】 • Move or archive dead links to any folder • Bulk-open and bulk-clean titles (strip " - SiteName" suffixes) • Exclude folders like "Archive" from scanning 【Rescue】 • Moved detection: site changed domains? Update to the new address in one click • Wayback rescue: check archive.org for dead links and restore the archived copy 【Insights】 • Bookmark profile: collection trends, top sites, dead-link rate, year distribution • Time Machine: on-this-day and random rediscovery, in a side panel or popup window 【Share】 • Export a curated selection as a themed web page (4 themes) or a long image 【Automation】 • Optional weekly incremental scan + weekly auto-backup • Badge shows pending items 【Privacy promise】 • 100% local: your bookmarks never leave your device — no upload, no collection, no sale • No account, no analytics, no ads, no third-party code • Sensitive permissions requested on demand, never at install 【Open source】 MIT licensed: https://github.com/LeafInCode/bookmark-cleaner
