There is, I’m pretty sure of it. But, I can’t remember where?!

That’s why you install Emacs and never look back. Everything you need in one program. No need to exit at all.

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?
