No. It works across all my systems. I never see ads on YT. However...
Videos not loading or playing delayed: That's a YT feature which they implemented for Firefox users, to annoy them. And to promote Chrome as "the fastest" webbrowser.
I also have dns issues at home... I should fix them already. Sometimes, a page doesn't load on the first try.
Oh, look! These Last Generation idiots causing a traffic jam again.
