Both Javascript and a plugin could work on a page-by-page basis.
You last sentence makes it sound like you intend to parse each page's
HTML and CSS to determine what font(s) it is using. Is that the case?
Because you'll end up reimplementing (quirks and all) a hefty chunk of
the browser's parsing engine if that's the case.
If you are willing to be less mysterious about the larger problem you're
trying to solve, we might be able to provide better advice. As it is,
we're left with a lot to guess at.
