This is a great extension, but recently it stopped translating? It just shows the hiragana pronunciation of the kanji without any more information. Not sure if this is a new bug or what? Edit - if you press D on your keyboard with a Rikaikun popup open, definitions come back!!

This addon just has so many problems when translated over to Chrome for some reason. I have no experience in the matter so I can't say for myself, but there are just so many annoying problems that just don't occur in Firefox. I wouldn't even be here bitching about it if I didn't have to use this horrible browser.

It was still usable some days ago, but now it decides to stop working completely, reinstall doesn't do any good either...

Quite useless. I click on it: it toggles on. Then I hover over Japanese text: no pop-up. Other times, I click on it to toggle on: nothing happens. I've uninstalled and installed several times. The Rikaichan version works on Firefox but it's buggy too. Rikaikun is totally unusable on Chrome.

Way too slow, devours the RAM, full of bugs, constantly crashes. Nevertheless, it doesn't work any more on my machine.
