Mozilla Unveils Kill Switch to Disable All Firefox AI features

Firefox 148 introduces comprehensive AI controls, including a centralized "Block AI enhancements" kill switch and individual toggles for features such as intelligent translation, PDF alt-text generation, AI-enhanced tab grouping, link previews, and a multi-model chatbot. The update emphasizes privacy and enterprise security by preventing automatic re-enablement of disabled features, offering Nightly access for early security evaluation, and positioning Mozilla as favoring user agency and security-first AI integration rather than describing a cybersecurity incident.
