Reverse YouTube Playlist by TRAD Aissa

Reverse YouTube Playlist lets you play any YouTube playlist from bottom to top with a single click.

When you open a playlist watch page (youtube.com/watch?v=...&list=...), a blue "Reverse" button appears in the playlist panel. Toggle it on, and when the current video ends — or
when you press Next — playback jumps to the PREVIOUS video instead of the next one. When you reach the top of the list, playback stops.

Features
- One-click Reverse toggle right in the playlist panel
- Works with autoplay and with the player's Next button
- Remembers the on/off state per playlist
- Stops cleanly at the top of the list (no wrap-around)

Privacy
This add-on is 100% client-side. It does not log into your account, does not use the YouTube API, does not modify your saved playlist, and does not collect or send any data. It
only stores a local on/off toggle in your browser.
