Mozilla Festival 2025

Le premier rassemblement pour celles et ceux qui œuvrent pour un monde numérique meilleur.

Rejoignez-nous à Barcelone pour fêter les 15 ans du 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.

Notre thème pour 2025 : désapprendre

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.
