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.
it's becoming more and more user hostile with every upgrade
pocket everywhere, telemetry, vpn ads, disney ads, amazon ads etc
(and despite the constant UI changes it still feels like something out of 1997)
