Users are furious at Firefox. After appointing new CEO Anthony Enzor-DeMeo, Mozilla promised Firefox would evolve into a “modern AI browser.”
On paper, that meant optional AI tools, summaries, chat sidebars, even integrations like Perplexity AI. But for a privacy first browser, even optional AI felt like a betrayal. The backlash was not just about features.
It was about trust. Firefox quietly removed language from its FAQ that said it would never sell user data. It introduced ad related systems like Privacy Preserving Attribution.
A complaint was even filed by NOYB over tracking concerns. Then new terms of use sparked panic about data rights. Mozilla later clarified the wording, but the damage stuck. Behind it all is money. Roughly 86% of Mozilla’s revenue comes from Google search deals.
With antitrust pressure on Google, that funding is at risk. So Mozilla is diversifying into ads, VPNs, and AI. Meanwhile, rivals like Brave are growing fast.
Brave offers AI and ads too, but they are off by default and clearly opt in. That difference in philosophy is everything. For Firefox, AI might not be the real problem. Trust is.
