Really interesting read about the history of YouTube adblocking, how the new detection works, how uBO is responding, and how not to block the new popups.
You can also get grayjay, which will also condense twitch, nebula, youtube, etc into one consistent feed without trackers or ads. Also it supports the down vote plug-in and 3rd party comment solutions so you can get even more from the app then you can with say revanced which is just the regular old YouTube app with patches.
