Google and Mozilla have struck a deal to extend their search agreement for another three years. Under the terms of the new agreement, Google will pay Mozilla $300 million per year to be Mozilla Firefox's default search browser. Sources said the total amount of $1 billion was the minimum revenue guarantee for delivering search queries garnered from consumers using Firefox. Google’s main rival in the bid was Microsoft’s Bing search service.

According to ComScore, Microsoft's Bing has reached 15 percent market share at the expense of Google and Yahoo. Bing's share rose from 14.8% in October to 15% through November, while Google dipped from 65.6% in October to 65.4% in November. Bing's increasing market share may is probably not a cause for concern for Google, who has consistently maintained 64% -66% market share.
