Forcing YT to use advanced tweaks for CPU usage optimizations

This userscript will remove the numbers of notifications, semi-advanced CSS tweaks along with forcing all videos to use the h.264 codec rather than VP9/AV1.

These are versions of this script where the code was updated. Show all versions.

  • v2025.09.28 2025-09-28
  • v2025.09.26 2025-09-26

    Added CSS to remove more annoyances including limiting related videos (apart from my YWT script).
  • v2025.09.14 2025-09-14

    Removed forced 30fps limit mode code because we need a seprate userscript or third-party extensions like h264ify to disable videos that are higher than 30fps.
