@Hadden89, at least none from the Chrome Store, there will only be decaffeinated versions there, as also happens on Google Play on Android.

Meanwhile I'll loo in Greasyfork and OpenuserJS, if there is something usable.
In OpenuserJS, I found an script from a Vivaldi user, not related to this thread, but a interesting script
