> Logic: Quality 1080 by default. If your machine has 2 or fewer cores, quality 480. If anything ARM, quality 240. Yes, Google thinks all ARM machines are 5 times worse than Intel machines, even if you have 20 cores or something.

Can't he just change the default? It's not locked in to a maximum resolution of 240 is it, he could click the video settings and switch up the quality to 1080 or similar.

Seems a bit excessive for him to refer to this as "crippling Firefox" when it only takes a couple of clicks to sort it out.
