That’s the one I know. There’s also XMPP if you can use something less feature rich.

I use Adguard for this purpose. You need a license to access some features. But, it can block ads even on sites which directly serve ads

Your whole existence revolves around peddling ads before people can watch the ads they want.

Ah, what. Who wants or likes to watch ads at all?

You have to add a custom addons collection. That’s how.
