Nah, I did the following: I picked a video in my Youtube app that I know has 60fps options. Then I switched to Firefox, played the same video and checked the quality options. In the app, it gives you the options 720p60, 1080p60 for example. In firefox, it does not.
Does it work for you in Firefox mobile?
So you most likely wanted to say “and Samsung still sucks compared to Apple?” Google phones also run Android, you know.
