The majority of our revenue comes from the search functionality in the Firefox browser. Google is the largest source of revenue and in December 2011, we announced that we negotiated a significant and mutually beneficial revenue agreement with Google. This new agreement extends our long term search relationship with Google for at least three additional years.
