Aux ports are nice for versatility, even if I was already using wireless earphones. Along with being able to listen to FM right on your phone. It's features I don't use often, but occasionally. I wish the USB-C connector had the option with a clip. IR-blasters were useful and much fun. I never even used the actual remote to manage my LED strip.
I never realized notification lights just kind of stopped existing. But I don't miss them in light of always on displays. Under screen finger print readers is basically a dream come true. Having multiple cameras is nice. OLED screen is an absolute godsend. Overall I'm not unhappy.
Doesn't Firefox support extensions on iOS? I'm on Android and I'm currently using uBlock Origin and Dark Reader. I also use Lemmy through it, seems to work quite well.
