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

RE: https://marius.blog/firefox-155-ai-kill-switch-retest/ Mozilla released Firefox 155 yesterday, so I took another look at its AI kill switch. The switch has grown since Firefox 148, but telemetry and advertising remain active. I retested it with Wireshark, and Mozilla’s internal reaction to my previous findings became part of the story too. #Firefox #Mozilla #AI #Privacy #OpenSource
