Mozilla may be a non-profit organization, but that doesn't of course mean it's not interested in raising some cash on the sides. Even if the court of public opinion says otherwise. Months after it launched its contentious Directory Tiles, it has rather silently started pushing its perhaps even more criticized Suggested Tiles feature to the Firefox browser. Unlike the previous Directory Tiles, this one is clearly, and formally, more advertisement centric. But don't worry, as Mozilla claims it hasn't made a profit from it. Yet.
