I have firefox (www-client/firefox-22.0) compiled with LINGUAS="es_AR", but doesn't start UI in spanish. The only way i can find is start on console with "firefox UILocale es" /etc/portage/make.conf LINGUAS="es es_AR" Reproducible: Always Steps to Reproduce: Start Firefox from KDE Menu. Actual Results: Firefox Menu in English Expected Results: Firefox Menu in Spanish
Wow I note that KDE neither is honoring LINGUAS. Sorry maybe is KDE the problem.
My mistake. /etc/env.d/02locale wasn't existed, the system variables wasn't configured LANG="es_ES.UTF-8" LC_COLLATE="C" Now it work well. Once again, sorry.
Fixed with this guide http://www.gentoo.org/doc/es/guide-localization.xml (es) http://www.gentoo.org/doc/en/guide-localization.xml (en)
Firefox source builds are configured to use locale defined by user now days. We do this so multi user systems can be configured for the user without forcing it via default config for firefox.
