I've been use Firefox for Android on 12 (and 11 before that) just fine, maybe an Android 13 thing? I can't remember the last time I used Chrome, I used Kiwi & Yandex at some points in the past and didn't notice any significant difference). If you are talking about smoothness, it's possible that I missed it, not caring much, but I've definitely never noticed it being so bad it becomes an usability issue.
yes. in 2022 on a top-spec phone and latest OS, scrolling of a static google results page or hacker news thread should not stutter. doesn't seem like an unreasonable ask, imo.
I've been using Android Firefox for years. I've rarely seen a scrolling issues. And those were decidedly not on static pages. Mostly the kind choked with ads.
