Hey Michael,

Yeah - the dtd for es-ES is using 8 bit encoding. It needs to be encoded in
UTF-8 for it to work. You can usually test the locales by changing your
general.useragent.locale pref and then restarting Firefox. I think there might
be another problem with it too - I converted the encoding to UTF-8 but now
there is a problem at &targetalert.menuitem.label;. You can point people to
http://forecastfox.mozdev.org/tutorial.html - it explains how to get the
encodings right.
