13th December 2021: Seriously, i'm not joking, with some pretty easy methods it is possible to watch YouTube with Firefox 48 on Windows 98 Second Edition, a 22 year old OS for 2021.
That's just incredible, really, and it's pretty good to watch the videos, best at 360p-480p max.
With 720p, also without 60 fps, it starts to have a little lag, but the exprerience is quite good, at 1080p instead is very laggy, and is not reccomended to watch at that quality.
You can't really see how it's good to play 24, 25, 30 fps video while i recording the screen unfortunately, and it can also go on full screen, wow!
But obviously, don't expect a fast experience of the browser.
