No, it's not. Every few months there's a new garbage "experience" released under a new about:config setting. Playing whack-a-mole with ads from the browser by navigating through a scary-looking UI that warns you that it's dangerous is not an experience I can recommend to family or friends.
Just set new tab to blank page. Thats where they live anyhow right? I haven't seen any of these ads people complain about and I suspect its because of my new tab setting.
