But I Don't Read Japanese

(Full disclosure: I have a familial Yahoo! bias.) I'm all for software trying to "do the right thing," but this is just silly. I'm sitting here in Japan and do a quick search on Google. (For some reason my Firefox insists on switching back to Google every now and then. I'm sure it's me, but I don't know what I'm doing.) It gives me results from google.co.jp... in Japanese. That makes sense, and I've noticed this behavior in many other places as well. Only one problem. I can't make it give me English results. I type in google.com, changed the URL, and it keeps sending me to co.jp. I figure that one of the links is preferences, but the language list is in Japanese as well. Luckily (?) the internationally popular "Elmer Fudd" language is written in English. Be vewwy, vewwy quiet...
