Greasy Fork

After the new YouTube update, the script doesn't work well; sometimes it consumes too many PC resources. Looking at the script's page, I saw that the last update was in February, which explains why the script isn't working properly.

This script is kind of independent of YouTube engine changes.

You can try https://greasyfork.org/en/scripts/494219-youtube-cpu-tamer-by-dommutation as well.

Or the issue is due to YouTube update itself, not related to this script.
