Keep or Delete Bookmarks is a Firefox add-on designed to streamline bookmark management. It randomly presents one bookmark at a time, allowing users to decide whether to keep, delete, skip, or open the bookmark in a new tab. This intuitive process helps users efficiently organize their bookmarks while ensuring they never see the same bookmark twice in a row. Users can also utilize keyboard shortcuts for quick actions, enhancing the overall user experience.

The add-on automatically checks if bookmarks are functional, and it features a whitelist for kept bookmarks and a skip list for unverifiable domains. Users have control over their decisions with confirmation dialogs for deletions, which can be disabled if preferred. The extension supports multiple languages and includes optional permissions for enhanced functionality, making it a versatile tool for Firefox users looking to declutter their bookmark collection.
