Worked perfectly for a while. Though for some odd reason, would eventually make YT unusable with it always not loading the rest of the videos for some reason. It also seems to make a conflict with adblockers as I started getting YT ads while using them and it disappeared after disabling this extension. At that point, it's a question of which I'd like to keep, and I obviously decided to go for my adblock and uninstalled this extension. I'm not sure if this will ever get fixed. I've been experiencing this same problem a few months ago and tried to give this a go again recently, but unfortunately, I started getting the same experience as what I said above.
