Firefox now has a full AI opt-out toggle, and almost nobody has touched it.
After vocal pushback from its privacy-focused user base — particularly around a CEO announcement — Mozilla added a kill switch to Firefox letting users disable AI features entirely. CEO Anthony Enzor-DeMeo confirmed this week that just 1% of users have flipped it off. Another 3% disabled some features selectively. The remaining 96% left everything on by default.
The optics cut both ways. Mozilla can credibly claim it listened: users demanded a kill switch, and Mozilla built one. But that same 96% passive opt-in is now a useful data point for anyone asking whether Firefox's user base objects to AI integration — the answer, it turns out, is mostly no. Enzor-DeMeo's framing that the value lies in the choice rather than the adoption rate is technically accurate and conveniently sidesteps the more telling number.
Mozilla has spent years positioning Firefox as the privacy-respecting alternative to Chrome. The kill switch extends that brand promise while quietly giving the majority of users permission to stay opted in — the rare feature that works as both a concession and a market signal.
