FavBox is an open source browser extension that enhances and simplifies bookmark management without cloud storage or third-party services

A pop-up window shows "Scanning your bookmarks..." with a progress bar at 44% and an explanation of the scanning process.

It extends your browser’s native bookmarking features.

Key features:
🔄 Syncs with your browser profile
🔒 No third‑party data sharing. No ads. No tracking.
🎨 Minimalist, clean UI
🏷️ Tag support for easy organisation
🔍 Advanced search, sorting, and filtering by tags, domains, folders, and keywords
🌁 Multiple display modes
🌗 Light and dark themes
🗑️ Detects broken and duplicate bookmarks
⌨️ Hotkeys for quick search access
🗒️ Local notes support
❤️ Free and open source

Something I found very useful with this extension is it quickly showed me all the duplicate bookmarks I have as well as one’s with broken links, so I could clean those up.

The extension is available for Chromium based browsers right now, but there is work in progress for a Firefox version too.
