In tech, little things can have big consequences — in this case, a tiny search bar. Last night, Firefox made a surprising announcement: after 10 years with Google as its default search engine, it would be handing the tiny search bar over to Yahoo. On the face of it, it's a strange move. If you're looking for almost anything on the internet, Google is a much better way to find it than Yahoo is. But that small search bar isn't just a feature, it's a business. And it’s a business that reveals how Mozilla and Google could increasingly be at odds with each other.
