Bookmark+ by wellingtonsaam

Bookmark+ turns your browser's own bookmarks into an organized library — with tags, notes and thumbnails — without moving them anywhere.

Everything is saved in the bookmark itself, so your bookmarks keep working in the browser's bookmark manager, in sync and on your other devices.

What you can do:
- Tag bookmarks and filter by one or several tags; build Filter-Tags that group related tags.
- Write notes with paragraphs on any bookmark and search them.
- See every folder as a grid of thumbnails: covers published by sites (YouTube, oEmbed, og:image) or a capture of the page.
- Bookmark the current page from the side panel (Alt+Shift+D) with tags, notes and a thumbnail.
- Test links: dead pages are tagged #404 and unreachable sites #Server_Error — and untagged when they come back.
- Fix duplicates, keeping the copy with the most tags and notes.
- Import and export bookmarks (HTML), move folders and tiles by drag and drop, hide private folders.

Privacy: no account, no server, no tracking. Nothing is sent to the developer. In Firefox, quick capture is optional and off until you turn it on.

In Chrome, Bookmark+ replaces the chrome://bookmarks page with its manager.

Available in English, Portuguese, Spanish and French.
