Does not work in Firefox 153.0.3 on a 64-bit Win11 machine.

Edit: It seems like the problem is the h265 encoding, which FF doesn't appear to support out of the box?

Edit2: Seems to load fine on mobile.

Edit3: The most straightforward way to get these codecs is to pay MS one dollar or one euro. There's probably some alternative if you really, really don't want to give Microsoft your money. You also need to enable it in FF, as it is turned off by default. This Reddit post explains how to do that.

Your device manufacturer might have paid for it.
Try "this":[ms-windows-store://pdp/?ProductId=9N4WGH0Z6VHQ] and see if it works.
