This is an extremely useful add on. I've been using it for years now and was never disappointed once. Cant wait for a working version for FF 4, I'm seriously considering downgrading my FF so I can use this add on again.

will be very useful include a romaji pronunciation next to hiragana text (it's the same, i know, but i don't remember all hiragana alphabet, will be more faster reading with the western alphabet)... but still is a very good tool.

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.

Life saver extension. I really like that it tells you how the word is conjugated. I often write in words I hear people saying in a text field to get a quick translation of the word I want to know.

1.09 is missing; use 1.08 to install something Rated 3 out of 5 stars

Version 1.09 is corrupt. Use version 1.08 -- it installs.

Wonderful utility since the day it was born. Unfortunately, using Firefox 3.6.3 and rikaichan 1.09 with no additional MS or Logitech, middle-mouse button autoscroll causes pop-ups to stop working, which can be a bit of a nuisance.

Bug? Rated 5 out of 5 stars

Since I installed the last update, I can't write in Japanes, something seems to be messed up with my IME support and I'm quite sure it's about rikaichan's last update

Living in Japan is not easy, mainly because everything is in Japanese.
there are some things that google translate just can cope with, and this is where rikaichan comes in play.
translates everything, really accurately and helps you learn along the way.
really REALLY good.
