I didn't believe it and after trying those samples, I still don't. All of them run flawlessly for me on FF 104.0.4 on an up-to-date Arch install on my laptop.
Also not seeing any issues, on Firefox 140.0.1 (via Flatpak) on Aeon (GNOME, Wayland). Everything's at my screen's native 165fps (except for the very first aquarium demo, which bottoms out at around 45fps with the maximum number of fish).
Wayland or X11? I'm on Kubuntu and from what I remember reading a while back it may be Firefox using something native on X11 that Chrome rolls its own thing for, but I may be misremembering.
