Doug Caverly digs up the most recent figures that illustrate just how important Google's search revenue is for Mozilla's
bottom line. In 2006, "Mozilla received about $56.8 million--or 85 percent of its revenue--thanks to the deal," he says. Numbers like that are what enable Mozilla to keep developing products like the
Firefox browser, which has gained favor with nearly 20% of all Internet users in the U.S., according to some reports.
And while the deal extension gives Mozilla bit of breathing room to either launch its own revenue-generating product (as Firefox is free) or find another well-paying partner, it will likely serve as more fodder for critics who feel that the company's ties to Google are already too binding.
