Disable YouTube video & screen based ads at home page, and right before or in the middle of the main video playback. Also disable YouTube's anti-adblocker popup dialog. As of now, it only work on embedded player.

Here is another shot of this tmp file info. Its whats doing it.
It still works sort of on Firefox with tampermonkey with adblock plus. I tried Ublock origin it works but after about 10 mins it lags the crap out of FF to not usability. Seems to be this tmp file youtube is sending (illegal computer misuse act) which just lags you to death. Look into it bro please if you have the time thanks man.
