方便查漢字的小工具。 以後學日語看到不知道讀音的漢字可以很方便查到讀音了。

I super like it. I want to give it 7 starts but only 5 are available. So, it's a 5 star high 5 for this.

This extension is awesome!! I tend to read a lot InuYasha fanfics, and sometimes the author a story will put the kanji in the story, and I would always think, 'I wonder what these kanji mean' but now I just hover my mouse over them and read the pop-up!!! though. i'd like to have more than the first tab of options... but other than that, THIS IS ONE OF THEE BEST EXTENSIONS I'VE EVER HAD!!!!

Great. Love it. Anyway I could be easier for beginers if it has an option to show Romanji

It's a pretty good extension. It works pretty well. But I think it would be much more great if it could translate the words on a HTML file.
