My Wireshark test of Firefox 148 showed that its AI kill switch disables generative features, but leaves telemetry and advertising untouched. Six months later, Mozilla’s CEO has called the switch perhaps the most important AI feature of all.
I retested it in Firefox 155.In this articleHumility as strategyThe comment section runs its own testRetesting Firefox 155The switch has grownTelemetry does not understand “blocked”Advertising continues, and Temu says helloTante reads the essayThe most important switch Firefox promises to protect users from companies spying on their clicks during onboarding. The AI controls are not mentioned anywhere in that flow. Screenshot: Marius Quabeck. My first test of Firefox’s AI kill switch apparently reached readers I had not expected. I was told that the article made its way into Mozilla’s internal Slack and was discussed there. The verdict: a “hit piece.” The fact that my previous Firefox article had been featured on the cover of the US edition of Linux Magazine probably did not help.
Anyone who read it will know that its core consisted of preferences, host lists, and timestamps. The reaction is nevertheless unsurprising. It is a familiar response when someone holds Mozilla’s own behavior up to the company. It is not my fault if Mozilla does not like what my tests revealed about its own behavior.
