The only thing that isn't quite on par (for me?) is 60fps videos. Those only play on 30. The 60 option isn't available. Maybe that's a codec incompatibility?
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.
These two together made me disable the YouTube app on my phone. Firefox is just a much better way to view YouTube.

60 FPS videos are only available at 720p and above, so maybe your browser is defaulting to 480p?

Does it work for you in Firefox mobile?
