Why can't web browsers block pop-ups?

It's been 31 years and web browsers are still utter trash. The developers at Safari, Firefox, Chrome and every other browser should be ashamed for allowing Pop-up and pop-under windows to even exist. It's functionality which needs to go away. If I don't explicitly open a link in a new window, that link should never, ever, EVER open in a new window.

Why is this still acceptable behavior? It has zero benefit to any end user.

Likewise, does anybody ever click Yes to browser notifications? That seems like it would be so intrusive.
