Rated 5 out of 5 stars

Not sure what went wrong for Johannes Rohr or nanfor.

Music Player Minion worked perfectly on my XP and Ubuntu FF 3.6 installs.

Perfectly. Couple of clicks, restart FF, click 'Minion', enter server, ok, MPD server is playing music.

This review is for a previous version of the add-on (1.4.4).
