The feedback in the responses leads me to believe my ear may have been too close to the loudspeaker, but here is a quote attributed to Mozilla Marketing leader Asa Dotzler in 2009: “Firefox users have their choice of several built-in and popular search services including Google’s number 1 competitor and the second most popular, Yahoo!. Google is the default for most Firefox locales because it’s the best search service available for the largest number of Firefox users (and was years before there was any revenue associated with default status).”
