YouTube Scrollable Fullscreen автор Waldoocs

As of August 2025, 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 made to add the function back to the youtube video page.

This works with both the OLD UI and NEW UI.
This works as of OCTOBER 2025
