» Thunderbird Send Button Problem
Thunderbird's send button may not work with Rikaichan 3.00 installed. This has been fixed in 3.01 which is currently queued for Mozilla's approval. If you want to try it now, you can download it from the Beta Channel:

» Version 3.01b1
(right-click/save as, or drag into Thunderbird's addon window)

If you just want to go back to the last working version, please install 2.09 from the Release Channel:

» Version 2.09
(right-click/save as, or drag into Thunderbird's addon window)

Unfortunately, you will need to install these manually in Thunderbird:
» Installing an Add-on in Thunderbird

» Installing in Thunderbird?

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.
