"A little off" (probably).

There is work at the W3C on how to specify fonts to be downloaded for a
document.  That is probably what the new feature Firefox added is based (but
I haven't looked at it, so this is just a guess).

We are working on adding support for the STIX fonts to MathPlayer.  At this
time, MathPlayer can't make use of them -- they are laid out in one of the
internal font mappings that MathPlayer currently can't handle and so even if
the STIX fonts are on your machine, MathPlayer won't use them.  Using them
should definitely improve the look of MathML rendered by MathPlayer.
