Just read about it in some local major news site, your report is much more extensive and better so thanks!
Just found out that the same method have been used in local popular sites in my country - affecting about 4 million users (in a country of about 7 million!) so that's a big risk :(
Apparently Adblock plus claim they did block Coinhive with the "easylist" filters but I am not sure if it covers the new method you mentioned so better just install that app you suggest too.
