Comment 1 for bug 69617

...better yet, don't let firefox suggest "movie player" (i.e. totem) unless there is good reason to believe it can handle the stream type. I typically have installed xine, amarok, and mplayer, all of which could handle mp3s.

And while I'm at it, you do realize one has to *browse* through /usr/bin if you want firefox to open a different application? There has to be a better way -- how about firefox present the choices from gnome/kde applications menu instead?

I tend to think that this is the single issue that makes Ubuntu less streamlined and newbie-friendly than Certain Other operating systems.
