Help and test instructions.

How to use

1. Install the extension in Chrome.
2. Open https://www.youtube.com/playlist?list=LL.
3. Use Scan visible or Auto scan to collect entries.
4. Filter by item type, title, channel, or duration.
5. Export JSON or CSV if you want a local backup with video links.
6. Run Unlike filtered only on a filtered set you have reviewed.

Troubleshooting

• If the panel does not appear, confirm you are on the Liked Videos playlist.
• If scan results look incomplete, use Auto scan and let YouTube load more rows.
• If unlike skips an item, YouTube may have changed the row menu or the item may be unavailable.
• Reload the page after a long YouTube session before running a large cleanup.

Privacy

The extension does not collect user data, call a developer backend, or load remote code.
