Lo que hacemos
A meetup to grow community, and create awareness about Open Source. This group is open to anyone who wants to collaborate and help us spread the Mozilla mission. Feel free to reach your local community.
Mozilla is a free software community which produces the Firefox web browser. The Mozilla community uses, develops, spreads and supports Mozilla products, thereby promoting exclusively free software and open standards.
In addition to the Firefox browser, Mozilla also produces Thunderbird, Firefox Mobile, the Firefox OS mobile operating system, the bug tracking system Bugzilla and a number of other projects.
