Volunteers are the heartbeat of Mozilla and MozFest is no exception. Our events thrive because of the time, dedication, and passion of our volunteers. By joining us you’ll get a unique, behind-the-scenes opportunity to see how this amazing event comes together. If you’re a Mozilla enthusiast or a supporter of internet health, volunteering is a fantastic way to contribute to our mission.

There is a wide range of volunteer roles including registering participants, managing welcome desks, assembling swag bags, assisting with speakers, and more!   We ask for up to four hours of your time, and in return, you’ll gain valuable experience with a global community. Plus, you’ll receive exclusive swag, access to MozFest sessions, and a personalized participation letter.
