Firefox's AI Switch Is Off. Telemetry Isn't

Firefox's AI kill switch disables generative AI features but leaves telemetry and advertising active, according to testing by security researcher Marius Quabeck. Mozilla CEO Anthony Enzor-DeMeo later acknowledged the criticism surrounding the browser's AI implementation, calling for better user control and transparency after initially defending the optional features as giving users choice. The incident highlights a disconnect between Mozilla's privacy messaging and its actual data collection practices that many users misunderstood as being addressed by the AI controls.
