coming out of lurkerdom to drop this link to 8chananon's YouTube player, recently updated:
https://8chananon.github.io/dl/yt-player.htm
anon has been using this player for nearly a year in the course of copious YT research
it removes all ads and doesn't leave crumbs to feed algorithms
my machine was being burned alive by the malicious CPU overload scripts that YT deployed last year against those running adblockers
thank you 8chananon for your coding and generosity in sharing this tool
God bless anons in all their capacities
