If you are interested in a search engine results page which is of Google results via a different country from your current location then use a proxy that is in another country. Go through that proxy, and if they have the option, get Google results via other Google's: Example Google.com (USA) or Google.fr (France) or Google.it (Italian), etc. The reason for the proxy is to block Google from knowing that it is you that are the same person looking at the various search results, in which case they might skew the results and lie to you.
MozBar and every other browser plugin for this (as far as I know at this time) is a waste of your time.
