If you do a google search for clearkey, the first hit is:
https://simpl.info/eme/clearkey/

That's a Google demo, and it works in Chrome but not in Firefox. That page uses EME in src=url WebM video, which we block.

FWIW, this demo works fine if I set media.eme.mse-only=false.

FWIW, EME in non-MSE WebM works in both Chrome and Firefox (when preffed on in Firefox), but EME in non-MSE MP4 fails in Firefox and Chrome.

MP4 in non-MSE video test case:
