• Total Adblock: This is considered the best ad blocker for YouTube and effectively removes YouTube ads as well as pop-ups, cookie notifications, and more.

• NordVPN Threat Protection: This is another ad blocker that is trustworthy and effective at blocking YouTube ads.

• AdGuard: This ad blocker is also effective at blocking YouTube ads, but there have been reports of it being targeted by YouTube in 2023.
