The 2026 edition of the Mozilla Festival (MozFest 2026), an annual global gathering organised by the Mozilla Foundation, will be held again in Barcelona, Spain, from October 28 to 30, this time at the Recinte Fabra i Coats, a former industrial complex turned cultural powerhouse.
The Festival, which is a mix of conference, workshop, art festival, and activist gathering, will bring the MozFest community together for three days of conversations, hands-on building, and exchange of ideas as part of efforts to imagine and build a better technology future.
Although the full details for MozFest 2026 have not yet been officially published, a theme and a call for session proposals will soon be announced, according to Ms Zeina Abi Assy, an award-winning curator, cultural producer, writer and designer, who serves as the Director of the Mozilla Festival at the Mozilla Foundation.
The Mozilla Festival, which began 15 years ago as a grassroots event, bringing together activists, technologists, journalists, artists, researchers, entrepreneurs, and policymakers to discuss the future of the internet, digital rights, and trustworthy technology, has since grown into a global movement for a healthier internet. The Festival provides an opportunity for participants to explore, collaborate, and share bold ideas.
The 2025 festival took place in Barcelona from November 7 to 9. The Mozilla Foundation, signed a three-year partnership with the city of Barcelona running through 2027, meaning that the festival will likely continue in the city until 2027.
The Festival, Mozilla’s largest public event, features hundreds of sessions, workshops, and labs, community-led programme design with participation from dozens of countries and a strong focus on human rights, democracy, and the future of technology.
It is one of the main global spaces where organisations working on freedom of information, media freedom, platform regulation, digital rights, and Internet governance can network, present projects, and influence policy discussions.
Founded in 2003, the Mozilla Foundation is a global non-profit organisation that exists to support and collectively lead the open-source Mozilla project. It sets the policies that govern development, operates critical infrastructure, and controls Mozilla trademarks and copyrights. It is the parent entity of the Mozilla Corporation.
