It's a great tool if you're trying to read single kanji's, but it's difficult to use when hiraganas are mixed in the words.

I've been using Rikaikun for years and it works great. Only thing is that it's missing some newer vocabulary terms as well as some expanded definitions/translations. If Jisho.org was integrated into rikaikun, that would be perfect. Also please consider adding the pitch shift number found in some dictionaries that can help with pitch accent pronunciation! For those experiencing problems with it opening up, make sure your chrome is updated and try re-adding the extension.
