Join us in Barcelona to celebrate 15 years of MozFest.
For 15 years, Mozilla Festival has been the home for big ideas, bold conversations, and the movement for a better internet. This year, we’re bringing that energy back to Barcelona, and you’re invited to be a part of it.
From November 7-9, we’re gathering the world’s most curious and creative minds for three days of workshops, debates, and hands-on collaboration to reimagine the role of technology in our lives.
This is your space to think differently, act boldly, and unlearn the internet as you know it.

Our theme for 2025: Unlearning
The future won’t be built by following old rules. This climate calls us to reexamine the systems, institutions and defaults we have all constructed and supported, and look with fresh eyes at solutions – not just critiques.

Host an Experience
Lead a session, run a workshop, share your art, or build something hands-on. The call for proposals launches later this year.
