Hi Gingerbread Man, I haven't researched how Firefox does font substitution; is it any more sophisticated than serif vs. sans-serif? I'm pretty sure there's no concept of equivalence for more decorative fonts.

For a user solution, I think you would need an extension to user script to modify the CSS @font-face rule (or related rules) to use your local copy of the font, or somehow override it.
