Empirical, but I have noscript and ublock enabled on Mozilla and whenever I go to youtube, it reloads three times in a laggy manner before it will let me type into the search. I check to see that I am not logged into gmail before using youtube. I am happy to do all that, because I like my videos uninterrupted and my web experience lean.
