Mozilla produces several open source products including the Firefox web browser, Firefox for mobile, Thunderbird email client, and Firefox OS operating system. Their strengths include an open source community, largest add-on community, and faster page loading times compared to competitors. However, their weaknesses include limited branding compared to Chrome, lack of focus on distinguishing features, and reliance on external developers. Opportunities exist in new mobile markets and growing internet users, while threats include dependence on companies like Google and potential users not seeing differences between browsers.
