YouTube - Disable Fullscreen Scroll
Disable scroll for details feature and remove the label from the bottom in fullscreen
This script will disable the "scroll for details" feature on YouTube when watching fullscreen entirely.
No more scrolling in fullscreen, just as it's supposed to be.
Note:
Due to how scrolling works in the browser, it is impossible to fully block scrolling. If you find a way to scroll, just try not to use it.
