Join us in Barcelona to celebrate 15 years of Mozilla Festival.

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.

Meet our headline speaker…

Dr. Ruha Benjamin, award-winning author of Imagination: A Manifesto, will join Nabiha Syed, Mozilla Foundation Executive Director, for a conversation to open Mozilla Festival 2025.

From the biases baked into our digital worlds to the myths that shape our laws and institutions, this conversation will explore how power operates through the stories we inherit. Whatever your background or perspective on technology, Dr. Benjamin will challenge our defaults to unlock new ways of thinking, building, and belonging.
