Very useful for me who is learning Japanese. It saves me a lot of time to search the meaning especially the furigana as I always forget the newly learned words.

Eu gostei muito,porém depois de um tempo ele para de funcionar... ele não traduz mais ele apenas dá a leitura da palavra e depois de um tempo nem isso, sem falar que ele as vezes não abre de maneira alguma! o que se torna ruim para quem depende desse aplicativo como eu!

Very useful, but why doesn't it work with offline files? I have to put the files on a local server and access them through localhost to be able to use rikaikun on them, because opening them directly with Chrome doesn't work :/

Nice plugin. Would it be possible to make it work like the google translate plugin? There you can select text then a popup appears allowing you to translate the selected text. This is not as intrusive and better for reading. (many people use the mouse cursor to follow text whilst reading) Thanks :)
