Localization in Firefox and Thunderbird

[Leslie Jensen]

Hello

I'm in doubt on how to do localization in Firefox and Thunderbird the 
correct way.

I've added these lines in my /etc/make.conf


# Firefox-i18n
FIREFOX_I18N=sv-SE

# Thunderbird-i18n
THUNDERBIRD_I18N=sv-SE



/usr/ports/www/firefox-i18n:make config

Here I've marked Swedish



/usr/ports/mail/thunderbird-i18n:make config
===> No options to configure


Even so after I upgrade everything is in English.

I would like to be able to keep the settings so that Swedish is the default.


Any advise on this?

Thanks
