Rikaichamp von Brian Birtles

Look up Japanese words with the hover of a mouse.

After enabling the add-on from the toolbar (or press Alt+R) simply hover over Japanese text and a popup displays corresponding dictionary definitions.

Use Shift/Enter to cycle through the available dictionaries (word dictionary, kanji dictionary, names dictionary), and 'd' to toggle hiding the definitions. You can use 'c' to select entries to copy.

Rikaichamp is similar to other rikai-tachi but aims to be simple, reliable, fast, and up-to-date. It includes simple installation, an always up-to-date dictionary, pitch accent information, definitions in multiple languages, and many many bug fixes over its predecessors.
