In Firefox, "MIDI Input" displays "not supported", even if "Computer Keyboard" is selected

In Firefox, "MIDI Input" displays "not supported", even if "Computer Keyboard" is selected.

That message is confusing, because when I hit keys, I can still see that they are being registered in the FaustIDE UI in the upper right, which implies that it's working - just webmidi should be marked as unsupported.

(Although, I can't seem to get "Computer Keyboard" to interact with the DSP smartkeyboard samples - which is the exact same behaviour that I get with Chrome; but it's also the same issue I have with mephisto.lv2 through carla, making me think that smartkeyboard is broken / not wired to MIDI; any ideas?)
