- Mozilla says Firefox will have an AI ‘kill switch’ in early 2026
- The move is an attempt to reassure users angered by its AI plans.
- Mozilla’s new CEO revealed plans to turn Firefox into an ‘AI browser’
AI is taking over the world, but not everyone is happy about it. This was aptly demonstrated by the swift reaction Mozilla received when the developer announced it would be adding artificial intelligence features to the Firefox browser, and now Mozilla has revealed its plan to placate angry users.
Writing on December 16, Mozilla’s new CEO Anthony Enzor-DeMeo outlined a plan to turn Firefox into “a modern AI browser” that will “support a portfolio of new, trusted software additions,” adding that the company would “invest in AI that reflects the Mozilla Manifesto.”
It was a point in a larger article about its goals for one of the best web browsers out there, but many readers took issue with its mention of AI and worried that Firefox would lose its identity as it chases the latest technology trends.
Now, Mozilla has responded to the furor. Writing on Reddit, Enzor-DeMeo explained that web browsers should appeal to a wide range of people, before adding: “Rest assured, Firefox will always remain a browser built around user control. That includes AI. It will have a clear way to disable AI features. A true kill switch is coming in the first quarter of 2026. Choice matters, and demonstrating our commitment to choice is how we build and maintain trust.”
The next day, Jake Archibald, Mozilla’s head of web developer relations, went to Mastodon in an attempt to clarify the situation. “One thing that hasn’t been made clear: Firefox will have an option to completely disable all AI features,” Archibald wrote. “All AI features will also be optional… the kill switch will completely remove all that stuff and never show it in the future. That’s unequivocal.”
Restore trust
Firefox has long attracted users precisely because it differentiates itself from its rivals. Unlike most browsers out there, it’s not based on Google’s Chromium engine and makes a deliberate effort to be as privacy-friendly as possible; In fact, it’s our pick for the best secure browser on the market.
Its principles have attracted people concerned about modern AI developments, whether about the overhead AI can add to a browser or concerns about how the technology will affect jobs, creativity and intellectual property.
I’ve been using Firefox continuously for over 20 years and one of the things that has convinced me to continue using it has been its long-standing commitment to privacy. This has hit a few bumps along the way, but nothing like the privacy concerns that plague companies like Google Chrome. At least in my case, trust has been maintained.
Yet it is exactly that trust that threatens the push toward AI. AI algorithms are a black box that users have no visibility over, and for now it’s impossible to know exactly how Mozilla plans to implement those AI elements.
Perhaps the main stumbling block is the lack of information in Enzor-DeMeo’s original publication. What is meant by an “AI browser” and a “portfolio of new, reliable software additions” is never clear, leaving people eager to fill the void. The sooner Mozilla can clarify its plans, the sooner it can regain trust and assure its users that it is not killing Firefox’s soul in the pursuit of AI innovation.
