Furigana plugin for Firefox?

[phalos]

Hello to all.

Does anyone know of a good plugin for firefox, to display Furigana kana above the Kanji? I use Rikaichan plugin, but I feel like I'm cheating for some reason.

Thanks in advance.

As far as I know, there aren't any that do just furigana and not the English definitions too, if that's what you're looking for.
