Totem plays midis in computer, not firefox.
|Ubuntu Desktop Bugs|
Binary package hint: totem
With the latest version of gstreamer, totem is able to play midi files. However, the totem-mozilla plugin does not register midi files as a mimetype (as seen in about:plugins), so even though totem can play them, midi files on the web still do not play. I believe that is a bug. I am using Ubuntu Hardy Herdon 8.04. I believe midis are important because websites often use them as they are really tiny in size.
