(Bloomberg/Agnee Ghosh) — Mozilla Corp. elevated the head of its Firefox web browser to chief executive officer of the company, which is trying to position itself as an independent, privacy-focused alternative to Big Tech options.
Anthony Enzor-DeMeo, most recently Firefox’s general manager, will succeed interim Laura Chambers in CEO job, Mozilla said in a statement Tuesday. As part of the change, Chambers will return to the Mozilla corporate board alongside company President Mark Surman.
Enzor-DeMeo faces a number of challenges as Mozilla’s new leader, including the dominance of Google’s Chrome browser and the broader disruption spurred by AI. But he sees privacy, transparency and greater user control as key advantages for Mozilla.
“The browser is AI’s next battleground,” Enzor-DeMeo said in the statement. That’s where questions about data use, transparency and user choice will be decided, he said.
Mozilla aims to stand out from rivals by making AI features optional and customizable inside browsers — rather than forced on users. The effort includes services such as “AI Window,” an opt-in assistant in Firefox that lets people choose different models and adjust privacy settings. There’s also a “Shake to Summarize” option available on Apple Inc.’s iOS operating system that received a special mention in Time’s best inventions of 2025.
Enzor-DeMeo, who joined Mozilla in 2024, previously served as chief product and technology officer at home-rental startup Roofstock and held product leadership roles at mortgage company Better and the e-commerce firm Wayfair Inc. He began his career at Dealer.com and holds an MBA from MIT Sloan School of Management.
Mozilla — backed by a nonprofit organization — said it will measure progress against a “double bottom line” of market performance and societal benefit. Over the next three years, it plans to prioritize AI that aligns with its goals and reduce the company’s dependence on internet search revenue as it adds more products.
AI chatbots have already begun to change the way people search the internet, and companies like OpenAI are preparing to transform the browser market as well. For now, though, Google’s Chrome remains a dominant entry point for the web. It accounts for roughly three-quarters of worldwide desktop browsing.
