Okay so you install this free mail program Mozilla Thunderbird then you have interfece in any language and then inside you see your own language [same as interface]. When you wil ltry to download extra languages it will not allow you with Thunderbird 10.
So how to change language in Thunderbird so inside email header/template will be in language that you want?
1. choose Tools –> Options –> Advanced –> General and press the Config Editor
2. type in mailnews.reply_header_authorwrote
3. change data to what ever you want ie:
user_pref("mailnews.reply_header_authorwrote", "%s wrote the following");
user_pref("mailnews.reply_header_ondate", "on %s");
user_pref("mailnews.reply_header_separator", " ");
Voila no more language issue in the email and header changed in thunderbird 🙂
