Thanks Abi.
I am really excited about this as this is my first contribution to
ubiquity source. I know it is
very small change but still I am happy that I got a start.
Regarding your comment in the trac, I thought of using
general.useragent.locale and also extensions.ubiquity.language pref,
but thought having a separate pref will give finer control to user.
