Adblock and Adblock Plus users report performance issues on YouTube, initially blamed on Google but later determined to be an issue in the popular ad-blocking extension.

Update 1/16 - Adblock has informed BleepingComputer that its engineers fixed the problem and released ABP 3.22.1 and AB 5.17.1 on the Opera and Edge extension stores. The same versions are currently in review on the Mozilla and Chrome add-on stores, and should be made available soon.
