Mozilla Appoints New CEO to Lead Firefox in AI Browser Wars

Mozilla has named Anthony Enzor-DeMeo as its new chief executive. The appointment was announced on December 17, 2025. The move signals a pivotal shift for the maker of the Firefox browser.

Enzor-DeMeo takes the helm at a critical time. The company is navigating a challenging market and a major industry transformation. His appointment comes as the company scrambles to adapt to the rise of AI in web browsing.

Firefox’s Strategic Pivot Towards Optional AI Integration

The new CEO outlined his vision in a public blog post. He confirmed Mozilla will invest in artificial intelligence. These new AI features will be added directly to the Firefox browser.

However, the company is taking a careful approach. Enzor-DeMeo stressed that all AI functionality will be optional for users. He stated that people should know how features work and the value they provide.

This strategy aims to balance innovation with user trust. Many Firefox users actively choose the browser for its privacy stance. Making AI opt-in seeks to respect that choice while still competing.

Navigating a Transformed Browser Landscape

The entire browser market is undergoing rapid change. Incumbents like Firefox, Chrome, and Safari face new competition. Companies like Perplexity, Arc, and OpenAI are baking AI models directly into their browsers.

According to Reuters, this represents a fundamental shift. Browsers are becoming the first point of contact for AI on the internet. Mozilla’s restructuring and layoffs last year show the pressure it faces.

Beyond AI, the company plans to diversify its revenue. A significant portion currently comes from its search deal with Google. Enzor-DeMeo wants to build Firefox into a broader ecosystem of trusted software.

This ecosystem already includes the Thunderbird email client and a VPN service. The company also recently launched an AI-powered website creator. The goal is to build a more sustainable future beyond the browser alone.

Mozilla’s new CEO faces the dual challenge of modernizing Firefox with AI while maintaining its core principles. The success of this careful balancing act will determine the browser’s relevance in the next chapter of the web.
