Mozilla added Firefox button to disable AI — only 1% of users used it

Mozilla added a feature to Firefox allowing users to completely disable all AI functions — following persistent demands from the community. The result proved paradoxical: only 1% of users actually used the kill switch.

Why the kill switch appeared

The request emerged immediately after Mozilla announced the large-scale deployment of AI features in the browser. Community reaction was unexpectedly sharp — particularly around the announcement of new CEO Anthony Enzor-DeMeo. Users demanded not just transparency, but a real management tool: a single button that disables everything at once.

Mozilla heard the request. Firefox gained a "kill switch" — a toggle that completely deactivates all AI features in the browser. In parallel, the company added more granular controls: Smart Window, VPN service integration, and other AI tools can now be configured individually. This step is atypical for the industry. Google Chrome, Microsoft Edge, and most other major browsers embed AI as an integral part of the product — without an explicit opt-out mechanism. Mozilla bet on transparency and gave users what they asked for.

Statistics after launch

When the new settings appeared in the browser, Mozilla began tracking audience behavior. The data presented by CEO Enzor-DeMeo looks like this:

• 1% of users completely disabled all AI features through the main kill switch
• 3% selectively disabled individual features through detailed settings
• 96% left everything at default — AI enabled, settings untouched

This is a well-studied UX research phenomenon: people highly value having a choice, but almost always use the default setting. Those who publicly demanded the opt-out tool mostly did not use it. The ability to control matters psychologically more than control itself.

It's also noteworthy that even the 4% of users who changed settings split differently: most preferred not complete disabling, but selective management. This speaks to heterogeneous attitudes toward AI — users are willing to accept some features while wanting to reject others.

Mozilla CEO's position

"Our community was quite active, especially at the moment of the CEO announcement, so we needed to provide choice," —

Anthony Enzor-DeMeo.

According to the company head, 1% is not a failure indicator. Firefox was never aimed at forcing users to reject AI. The task was different: to give the audience a sense of control and confirm that the browser doesn't make decisions for people. This is principled positioning against competitors. Google Chrome integrates Gemini, Microsoft Edge actively promotes Copilot — and neither offers a button to "disable everything." Firefox occupies a niche it created itself.

What this means

The story of Firefox's AI kill switch is a clear example of the gap between public demands and actual behavior. A loud demand for a control tool doesn't mean it will be used. But its presence changes overall product perception.

For technology companies, there are several takeaways here. First: providing users with formal choice reduces product resistance, even if almost no one uses the choice. Second: AI can be deployed confidently — there will be no mass rejection. Mozilla obtained rare public confirmation of both theses: data from a real browser, not from surveys.
