Firefox ignores the setting of $LC_MESSAGES=C and shows the UI in german, just
because I set $LANG to german.

Firefox should honour $LC_MESSAGES properly, just like any other good program.
Comment 1 Robert Marcano 2008-04-10 19:24:47 EDT
looks like the problem is the Fedora script used to launch firefox, it does
check that the language extension is installed using the LANG. That script is RH
specific, I removed the offending line and let firefox select the language by

With LANG=ja_JP I saw the UI in Japanese., with both LC_MESSAGES=en_US
LANG=ja_JP everything was shown on English.

Related lines on /usr/bin/firefox:

# Try without a local variant first, then with a local variant
# So that pt-BR doesn't try to use pt for example
SHORTMOZLOCALE=`echo $LANG | sed "s|_\([^.]*\).*||g"`
[ -f

MOZLOCALE=`echo $LANG | sed "s|_\([^.]*\).*|-\1|g"`
[ -f
