Reports of severe YouTube slowdowns were linked to a performance regression in Adblock and Adblock Plus (AB 5.17/ABP 3.22), not to Google throttling. Profiling indicated the extensions’ content scripts caused heavy page delays, especially on dynamic sites, while uBlock Origin was unaffected. Adblock has issued fixed versions (ABP 3.22.1 and AB 5.17.1), with availability depending on browser store approvals.
