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

Firefox’s AI kill switch disables generative features but leaves telemetry and advertising active, as confirmed by Wireshark tests on versions 148 and 155. Roughly 1% of users turned off all AI and 3% disabled individual features after the switch’s release. Mozilla’s CEO Anthony Enzor-DeMeo highlighted the switch as the most important AI feature, noting that most users kept translation enabled while rejecting generative AI.
