Till the developer self will extend the localizations, you can simple set it up as following:

- download the add-on data (currently, "filter_copy-0.2-tb.xpi")
- unpack it (XPI = ZIP)
- open the directory [unpack_folder]/chrome/filter_copy/locale and find the folder "ja-JP"
- copy the folder ja-JP as en-US (for the English localization)
- edit the file en-US/overlay.dtd. This contains only one configuration entry. So, in place of the Japanese text, write: "Copy".
- go to [unpack_folder] and edit the file chrome.manifest: Add the new line (analog to the existing line with "ja-JP"):
locale filter_copy en-US chrome/filter_copy/locale/en-US/

(The same steps should be done for each other localization, e.g. ru-RU, de-DE, fr-FR... etc. One new folder containing a translated overlay.dtd + one new line in the manifest file for each localization.)

Pack again as ZIP, rename the "ZIP" extension into "XPI" and install into Thunderbird.

恐らく、不具合なのではないかと思いますが、
コピーしたフィルタを編集すると元のフィルタの内容も変わってしまいます。
機能としては、非常に欲しいものですので、ぜひ直してほしい。

I'm a user but I describe what this add-on is.
This add-on provides you "Copy (in Japanese)" button in Message Filter window. You can see new button between "Edit" and "Delete" in the right of Message Filter window. (Unfortunately, the label for this button is only Japanese.) When you click this "copy" button after highlighting a Filter, then new filter with same condition is appeared.
