Strips the deprecate-fullerscreen-ui attribute everywhere on YouTube, early and repeatedly
The “scroll in fullscreen” mode you remember is gone from YouTube’s codebase. It was a hidden feature flag (toggled by the deprecate-fullscreen-ui attribute), and removing it would revert you to the old branch. Now, that entire branch has been ripped out, making this script unusable.
This userscript restores the ability to scroll while in fullscreen on YouTube.
YouTube recently removed this long-standing feature by adding an experimental attribute (
deprecate-fullerscreen-ui). This script removes that attribute so you can continue to scroll through comments, suggestions, and playlists while a video stays in fullscreen.
- Restores scrolling while watching videos in fullscreen
- Prevents YouTube from re-applying the restriction
- Works with YouTube’s single-page navigation (SPA)
- Lightweight and does not interfere with ads or other site features
1. Install Tampermonkey or another compatible userscript manager
2. Click the green Install this script button on GreasyFork
3. The script will automatically run on YouTube
- The script only targets the attribute responsible for disabling fullscreen scrolling
- It does not modify or block anything else on YouTube
