Mozilla Leadership
The Mozilla Project is a global community of people who believe that openness, innovation, and opportunity are key to the continued health of the internet. Today the organizations within the Mozilla Project are led by diverse teams of exceptional leaders, guided by our Executive Leadership Council.
Executive Leadership Council
The Executive Leadership Council includes the top leaders of each organization in the Mozilla family, as well as the Mozilla.org Executive Team. Along with our Boards of Directors, the Executive Leadership Council works collaboratively to ensure effective day-to-day coordination across Mozilla, and to drive Mozilla’s growth and progress as a double bottom line enterprise.
