It's AMAZING! but saldly to make it work u have to install it and uninstall it over and over again cause IT WILL STOP WORKING after 1 o 2 days without any reason, and it's always the same, it works for 1 day or 2 and then it stops, so, 1 star for the idea! 0 star for the bad programming of the app! :/

I love this!! It has helped me a lot while reading Twitter and other websites in Japanese. The best part is you can check in a fast and easy way the reading of the word you want and at the same time, see the English definition so is a great way to learn kanji and vocabulary. Thank you for creating this!!! I always recommend this extension to other Japanese learners.

I really like this extension, but it sometimes stops showing the English translations, so I have to remove the extension and then add it back again. This happens every couple weeks. ;(

great but would be better if: -they'd remove the pinyin entries -make it so "画像" doesn't pop up when you scroll over an image
