I only seem to barely notice the difference... At first i couldnt understand what everyone was talking about...but yeah its a small delay over what it used to be. Also it seems any bookmarked vids will no longer autoplay.... you have to click play... is that a thing anyone else has to do ?

I tried Edge and it seemed only a small bit faster to me, but it did autoplay. Are there any other anomalous strange effects google has done to youtube that i might have missed ?

I never had issues with adds on FF and ublock ... still don't.
