Mitchell Baker co-founded the Mozilla Project to support the open, innovative web and ensure it continues offering opportunities for everyone. As CEO of Mozilla Corporation, Mitchell is focused on accelerating the growth levers for the core Firefox browser product and platform, while investing in innovative solutions to mitigate the biggest challenges facing the internet. As Chairwoman of Mozilla for the last two decades, Mitchell Baker has been responsible for organizing and motivating a massive, worldwide, collective of employees and volunteers who are building the internet as a global public resource, open and accessible to all.

Mitchell is deeply engaged in developing product offerings that promote the mission of empowering individuals. She also guides the overall scope and direction of Mozilla’s mission. Mitchell has written the key documents that set out Mozilla's enduring mission and commitments -- the Mozilla Public License in 1998, the Mozilla Manifesto in 2007 and the Mozilla Manifesto Addendum -- also known as the Pledge for a Healthy Internet -- in 2018. Mitchell is a strong advocate for the open internet, open source, and the importance of connecting technology to its impact on individuals and society. She is highly regarded as one of the pioneers of the web and bringing the open internet to consumers. She was instrumental in Netscape’s decision in 1998 to release its source code to the public.

This later led to the release of the Firefox browser and the creation of the Mozilla Foundation as a global technology force that spans software product development, educational initiatives, and participatory movements. After co-founding the Mozilla Project, Mitchell served as its general manager and CEO from 1999 until January 2008, when the organization’s rapid growth encouraged her to split her responsibilities and add a CEO.

TIME Magazine profiled Mitchell in its global list of “100 Most Influential People” under “Scientists and Thinkers”. Bloomberg listed her as one of the “25 Most Influential People on the Web”.
