Foarbyld fan BookmarkIsAlive

BookmarkIsAlive troch Expression Inc.

A slow, polite link checker for your bookmarks. Defaults to at most a few requests per minute across all domains and one request per hour per domain. Sorts dead ones into folders by reason (404, gone domains, auth, redirects) without deleting them.

Metadata útwreiding

Oer dizze útwreiding
BookmarkIsAlive is a Firefox add-on that quietly finds dead links in your bookmark collection and organizes them — without deleting anything. Unlike typical "broken link checkers" that scan everything in a few aggressive minutes, BookmarkIsAlive runs as a long-lived background process with hard rate limits: by default at most a few requests per minute in total and at most one request per hour to the same domain, so it never hammers any server.

If something goes wrong: restoring your bookmarks from a Firefox backup

This add-on never deletes bookmarks — dead ones are only moved under a BookmarkIsAlive/ folder. If you still want to undo everything (or you accidentally classified bookmarks while testing), Firefox keeps automatic daily backups you can restore from in one step.
  1. Open the Library: Bookmarks menu → "Manage bookmarks..." (shortcut: Ctrl+Shift+O / Cmd+Shift+O).
  2. Click the "Import and Backup" toolbar button (star + arrow icon).
  3. Choose "Restore" and pick either a dated automatic backup, or "Choose File..." to load a .jsonlz4 / .json file.
  4. Confirm — your entire bookmark tree is replaced with the chosen backup.

Firefox's automatic backups live in your profile's bookmarkbackups/ directory:
  • Windows: %APPDATA%\Mozilla\Firefox\Profiles\<profile>\bookmarkbackups\
  • macOS: ~/Library/Application Support/Firefox/Profiles/<profile>/bookmarkbackups/
  • Linux: ~/.mozilla/firefox/<profile>/bookmarkbackups/

Up to 15 daily snapshots are retained by default (about:config → browser.bookmarks.max_backups).
