But bro we can't thing we cheat youtube everytime.

I use Alt+ left mouse click but nothing happened. Check your settings first. If anyone that you feel it is checked or not. May be after this your problem will solved.

Go to opera setting and scroll down to on startup and check open a specific page or set of pages is checked. It would not be check.

YouTube knows it's an ad blocker and blocks the video. YouTube has already gotten smarter. Also there are many ad blockers you can use.

Google block this extension on 2022.
