I'm not sure the degree to which this relates, but it /may/ have something
to do with the fact that mp3 is still patent encumbered (just a few more
years... 2016, IIRC), while ogg/vorbis is free of known encumberment. If
you've been watching the whole html5 thing play out, you know that's been
a big issue with the html5 native video tag as until Google's vp8 codec
release, the top two choices were the patent encumbered x264, which the
FLOSS community (including mozilla/firefox) couldn't stomach, or theora,
which Apple, etc, wouldn't accept. html5 native audio, OTOH, was rather
easier to resolve as all parties were apparently able to settle on ogg/
Now the chances of you running the firefox-4 prereleases with their html5
support isn't too high, but an educated guess would be that firefox 3.6
(earlier??) supports ogg/vorbis natively as well, but can't do that with
mp3 due to patent encumberment.

That would help clarify things, certainly. Perhaps the above provides a
pointer in the right direction to look... Before html5, of course, plugins
were the way both audio and video were supported, but it's quite possible
firefox has had native ogg/vorbis support for some time.
(BTW, ogg is simply the container format, while vorbis is the actual audio
encoding. While ogg has unfortunately commonly been used as an extension
for ogg/vorbis, that's technically incorrect, just as zip or tbz2 refer
not to whatever's contained, but rather, to the compressed container
used. Thus, when referring to the combination of container and audio
codec, I always use ogg/vorbis, while using simply ogg or vorbis, when
referring to the container or audio codec without its container,
individually. Altho, much like GNU/Linux, I accept that it's likely a
losing battle, because the full name is simply too long and cumbersome for
popular reference. (FWIW, I do normally simply use "Linux", myself, using
"Linux kernel" when I need that distinction, and only use GNU/Linux when I
need the distinction between it and say GNU/Solaris or Dalvic/Android/
Google/Linux. So I'm not /that/ much of an absolutist.))
