Firefox is the Web browser released by Mozilla, an open-source software organization. Firefox is free to download and use, and is compatible with many Web technologies. Firefox is seen by many as a strong alternative to Internet Explorer because of its comparable lack of security risks.
Firefox is an open source browser created by an international movement of thousands of people, only a small percentage of whom are actual employees.
Mozilla's mission promotes openness, innovation and opportunity on the web rather than business concerns like profits or the price of stock. And as a non-profit, public benefit organization, Mozilla defines success in terms of building communities and enriching people’s lives.
