Where Data Defenders Unite
Mozilla Festival is the gathering for people who believe privacy isn’t optional. Meet your ethical tech allies and co-create a better digital world.
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 3,000+ technologists, activists, educators, artists, and everyday users for three days of workshops, talks, labs, and art to reimagine the role of technology in our lives.
This is your space to think differently, act boldly, and unlearn the internet that trades on your privacy.
