Google in other countries

Hi Zonafirefox. I've tried it on different Google domains including the one you suggested and it is working for me. Could you post the URL that you used? I used http://www.google.es/search?hl=es&gl=es&q=barcelona&pws=0 and it works fine. Might be good to also check you are using Version 0.2
UPDATE: I think I've found the problem and fixed it in Version 0.3. If you see any other cases where it doesn't work then please let me know. Thanks.
