Rated 5 out of 5 stars

Rikaichan is up there with Firebug as my absolute favorite, indispensable addons. I never thought I'd need this as much as I do but to a non-native Japanese speaker with no Japanese acquaintences (or tv for that matter), it is truly essential. Just like user scantly I, too, type a word in a text field for a quick lookup. I now don't need google language tools to fill in forms in Japanese and it takes me much less time to get an overview on what is what on any Japanese page.

This review is for a previous version of the add-on (2.01).
