I use Youtube Center addon (a userscript version also exists on greasyfork) which has a hundred of various options, autostop included, but I guess you're looking just for this particular function so maybe one of these scripts will help: https://greasyforks.org/scripts/search?q=youtube+pause
@wOxxOm Very helpful :) Thank you.
