Rated 5 out of 5 stars
There is a reason why this extension will soon surpass 100,000 downloads: it is an indispensable tool for anyone who is studying Japanese at every level. In fact, it is worth switching to FireFox just to be able to use this extension! It isn't (as of this writing) perfect: the popup often pops under flash on the page. Even so, it is so useful that it doesn't really matter. Have to give this 5 stars plus a few extra.This review is for a previous version of the add-on (1.02).
