Bookmarks Health Checker is a free Chrome add-on designed to help users manage their bookmarks effectively. This tool checks for broken links within registered bookmarks, allowing users to identify and remove any that are no longer valid. The process is straightforward: users select a bookmark group, initiate the health check, and review the list of broken bookmarks presented in a dialog box. Users can then choose which bookmarks to delete with a simple click of a button, streamlining the organization of their bookmarks.

In addition to its core functionality, Bookmarks Health Checker offers customization options, including the ability to switch between 22 theme colors and light/dark modes. Users can also adjust the health check timeout settings, ranging from 500 milliseconds to 10 seconds, to suit their preferences. Recent updates have introduced features like language switching and resolved bugs related to bookmark state management, enhancing the overall user experience.
