Yahoo is Firefox default search engine in US

San Francisco

YAHOO! Inc has replaced Google Inc as the default search engine on Firefox browsers in the US as Yahoo chief executive Marissa Mayer seeks out more partnerships to boost the Web portal's traffic and revenue.

Google had been the automatic search option for the Internet browser, developed by Mountain View, California-based Mozilla Corp, since 2004. Under the agreement announced, Google, Microsoft Corp's Bing and other search services will be available as alternatives, No 3-ranked Mozilla said in a blog post.
