I guess this wont be a Debian specific problem. But could you please check if this problem is also existing in packages from Mozilla. https://www-dev.allizom.org/en-US/thunderbird/ And as we can't write or understand japanese language at all could report this issue afterwards on the Mozilla bugtracker? You cann add there some screenshots to if this is helpful. https://bugzilla.mozilla.org/enter_bug.cgi Thank you! Regards Carsten
