YouTube Center is a userscript designed to expand the functionality of YouTube. It includes the ability to download the video you're watching, auto selecting your preferred video quality and much more.
I have found many times that the Youtube Center script does not have any apparent effect, even though Tampermonkey claims it is on. Other times it will kick in, but far too late. I wish for it to stop autoplay, but if it starts working after two minutes of the video have played already, and stops it at that point, it doesn't help me as much. I'd prefer for the display of the page to wait until the script is ready, and this could be useful for any userscripts I suppose, but I'm unaware of anything to set in Tampermonkey or in Firefox to do that.
I'm using Youtube Center dev build on Tampermonkey on Firefox 52 ESR.
