out-of-date dictionary, they should update the entries with the ones in http://nihongo.monash.edu/cgi-bin/wwwjdic?1C: (the dictionary it seems they used for the application)

Incredibly useful for browsing. It has a surprising amount of knowledge about specific areas. For example, knowing 圏 as "category" in the context of category theory.

This is a fantastic app. It's one of the best and in some cases it's a make or break extention when determining which computer to use for work. I'd even say I'm very grateful to the developers. That said, it works well on Firefox and only there. Its cousin's potential here in Chrome hasn't been realized. This is the only reason I have fully switched to Chrome. I wish it would equally as well on both browsers. It's a huge disappointment that it so underperforms on Chrome. If you haven't used it on Firefox, you haven't experienced the full power and magic of this extention. Again, to the developer(s), I am profoundly grateful for this extentions development as it's been a great help. I'd even pay for this extention on a yearly basis. But I couldn't in good conscience recommend its use on Chrome when it so underperforms compared to the same extension on Firefox.
