Am I missing something? I've used this awhile ago but recently it's not working at all. Any ideas?

This is a great extension that I will be using whenever there's a kanji I don't know or a sentence I get confused over. But I can also see how it can become a problem after using it for a while, considering how it highlights near to everything and it does so right away instead of waiting until you hover over a character for a second or two. I also wish there was a way to disable hiragana and katakana reading for us who already know how to read those.

I've been looking for something like this for YEARS! Now I can finally say baibai to NJStar JP and be more efficient with my translations!

I use it on a daily basis...It comes in hand all the time...In fact I feel like I've memorized more kanji through rikaikun than anything else. A+ p.s. it enven has a pinyin reader for chinese! although it can't read all Hanzi it does read all Kanji
