For 15 years, Mozilla Festival has been the home for big ideas, bold conversations, and the movement for a better internet. 

From November 7-9, this festival will be 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.

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.
