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.
