As far as I am aware the time has come and as of Firefox 72 XUL has been stripped from firefox and so the method used to inject this scrollbar theme is no longer supported -- reference the following for future scroll themes:

Mozilla is currently working to phase out the APIs used to make this theme work. I will try to maintain each version until that time but eventually there will be no workaround. When that time comes there is a new, but more limited api for applying simple themes to scrollbars. In nightly I am currently using the following userContent.css

:root{
	scrollbar-width: thin;
	scrollbar-color: rgb(82, 82, 82) rgb(31, 31, 31);
}

// Date.now() is supported everywhere except IE8. For IE8 we use the Date.now polyfill
//   github.com/Financial-Times/polyfill-service/blob/master/polyfills/Date.now/polyfill.js
// as Safari 6 doesn't have support for NavigationTiming, we use a Date.now() timestamp for relative values

// if you want values similar to what you'd get with real perf.now, place this towards the head of the page
// but in reality, you're just getting the delta between now() calls, so it's not terribly important where it's placed
