Purchasing Adult and Youth Tickets

You must be 18 or over (“Adult”) to make a ticket purchase on our website.

Ticketed parents or legal guardians of individuals under the age of 18 (“Minors”) may register and attend MozFest sessions with their Minors. Parents/Guardians should supervise Minors’ participation in MozFest. Mozilla does not supervise Minors’ participation or screen events for appropriateness for Minors. Events may include the participation of other MozFest attendees, whose actions Mozilla does not control. Parents/Guardians agree to be responsible for their Minor(s) at all times.

Each ticket has a unique number, which allows for one person’s entry into the festival. Keep your order details safe, as we may not be able to admit you to the festival if the number on your digital ticket has previously been used.


Ticket purchases are final and nonrefundable. However, if the event is cancelled by us, you will be entitled to a full refund of the amount paid for your order.

Ticket Transfers

Tickets may be transferred to another person immediately after the purchase is completed or through the link provided in the confirmation email. You can also request to transfer your ticket up to 10 working days before the event by emailing festival@mozilla.org

Ticket assignees will be required to agree to the Event Terms and Conditions in order to claim the ticket.
