ClearMark: Bookmark Cleaner & Duplicate Remover

ClearMark is a powerful bookmark cleaner and link organizer designed to keep your browser fast. Over time, saved links go dead, silently redirect, or pile up as duplicate bookmarks. ClearMark finds every broken link and 404 error in one background scan, allowing you to cleanup bookmarks in minutes. Key Features * Remove Duplicate Bookmarks: Automatically find and delete duplicates to declutter your folders. * Fix Broken Links: Identify dead bookmarks, 404 errors, and server timeouts that slow you down. * Redirect Manager: Detect bookmarks that have permanently moved and update them to the final URL. * Bulk Cleanup: Delete or update hundreds of links at once with one click.
