Strips the deprecate-fullerscreen-ui attribute everywhere on YouTube, early and repeatedly
As of 2025-08-28. See the latest version.
These are versions of this script where the code was updated. Show all versions.
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. The script has now been updated to add the function back to the youtube video page.
