Description of problem:

Firefox 1.5.0.5 uses a add-on based locale support. However, /usr/bin/firefox 
still expects the locale file to be located in the old filesystem layout, and 
is unable to locate any locale beside en_US. Therefore, Firefox will start up 
in en_US locale regardless of the system locale settings.

Version-Release number of selected component (if applicable):

1.5.0.5-0.el4.1

How reproducible:

Always.

Steps to Reproduce:
1. Set e.g. LANG=de_DE.UTF-8
2. Run /usr/bin/firefox
3.
  
Actual results:

Firefox starts in the US English locale, regardless of $LANG.

Expected results:

Firefox should start in the locale specified by $LANG, as long as there is an 
Firefox langauge add-on present.

Additional info:

This problem can be easily fixed by updating /usr/bin/firefox, line 142 from:

[ -f $MOZILLA_FIVE_HOME/chrome/$MOZLOCALE.jar ] && MOZARGS="-UILocale 
$MOZLOCALE"

to:

[ -f $MOZILLA_FIVE_HOME/extensions/langpack-${MOZLOCALE}@firefox.mozilla.org/
chrome/$MOZLOCALE.jar ] && MOZARGS="-UILocale $MOZLOCALE"
