If you haven't noticed or don't know already, Google is the default search engine when you install the Mozilla Firefox web browser. But have you ever wondered why? Google pays Mozilla to make their search engine the default for the Firefox web browser and Google pays pretty well to keep it that way. Mozilla is a non profit organization and relies on Google's support to keep them going. In fact, Google's money accounted for 84% of Mozilla's $123 million in revenue for 2010.
But this partnership does not go just one way. Google relies on search traffic from the millions of Firefox users around the world and is willing to pay to keep others such as Microsoft and Bing out of that share of users. With their new contract, Google will be paying Mozilla almost 3 times as much per year as they did before at a cost of $300 million a year for the next 3 years. This price increase may be the result of other bidders such as Microsoft trying to get a piece of the Firefox pie.
