Purchasing Adult and Youth Tickets

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

Adults may purchase Youth tickets (for ticket holders under the age of 18) on the MozFest website. Youth under the age of 16 will not be admitted to the festival unless they are accompanied by an Adult holding an Adult Weekend ticket. Adults will be required to sign a Parent/Guardian Consent form and to add their contact details to the Youth ticketholder’s name badge; they agree to be responsible for the Youth ticketholder at all times while on site and to be contacted in case of emergency.

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.


Tickets purchased on our website are subject to Great Britain's VAT rate (20%), which is shown on the checkout page and on your receipt after ordering.

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.

Promotional Codes

Certain guests are provided with promotional codes for purchasing discounted ticket. We reserve the right to cancel tickets purchased with unauthorized promotional codes.
