I am an English speaker and, regrettably, a few basic pleasantries in many languages aside, only an English speaker. I use Firefox as my preferred browser with the built in Google search bar. Google is also my favorite search engine.

The problem is that when I travel abroad to a country with a foreign language, Google figures this out and automatically assumes that I understand and would prefer to read the local language. For example, I am in Argentina right now. When I do a Google search, it throws me into Google Argentina with Spanish everywhere. Some of the search results still point to English language pages, but the information at the top is purely in Spanish. For example:
It looks like I should be able to change my "Preferencias" to make English the default, but this is only a temporary fix. And amazingly, in this instance, http://www.google.com.ar/ doesn't have an English language choice; the options jump from "elmer fudd" to "eslovaco."

Other than bookmarking http://www.google.com/intl/en/ and manually opening it up in a new tab every time I need to do a search from abroad, is there any way to make English my one and only language in Google so that I don't have to fight a language battle every time I travel to a non-English speaking country?
