Reading Bookmark Cleaner by Rafis

Reading Bookmark Cleaner helps clean up old chapter and episode bookmarks from your Firefox reading folders while keeping the newest bookmark for each series.

It is designed for people who bookmark manga, manhwa, web novels, light novels, anime episodes, and similar chapter based pages. The extension scans a selected Firefox bookmark folder, groups likely matches by site and series, shows which bookmark it plans to keep, and lets you review older bookmarks before moving or deleting them.

Features:

• Scan a selected Firefox bookmark folder
• Choose whether to include subfolders when scanning
• Detect chapter and episode numbers from bookmark titles and URLs
• Group bookmarks by site and series
• Keep the newest chapter or episode bookmark for each series
• Review older bookmarks before cleanup
• Move old bookmarks to a review folder instead of deleting them
• Delete old bookmarks only when you choose to
• Undo the last move operation
• Export bookmark scan results to an Excel friendly CSV file
• Use a saved light or dark view
• Leave low confidence matches unchecked by default for safety

Reading Bookmark Cleaner runs locally in your browser. It does not send your bookmarks, browsing data, or personal information to any server.
