How does one add content types to Firefox

[Macario Valle]

There is:
there is an addon called "Force Content-Type".  I do not know how to use
it but have seen my friends make changes like having their favorite
media player configured manually instead of the default ones.  I will
ask around and see what I can learn.  Never bothered with stuff like
that as I do not ussually play videos and games; got no free time.
