Dictionary Files

Please install one or more dictionary files to use with Rikaichan.

Unsigned Dictionary Files

The files listed below are updated more frequently than those listed above, but are not "signed." These files will only work on Firefox versions that do not use signature verification or on versions that will allow you to disable it. Examples: Firefox ESR, Firefox Developer Edition, "Unbranded" Firefox.

Thunderbird can use both signed and unsigned addons.
