Mozilla has released Firefox 148, marking a significant step in the browser's approach to artificial intelligence with the introduction of centralized AI controls and a global kill switch. This update moves the AI kill switch from beta to the mainline release, allowing users to completely disable all AI features—a direct response to community feedback following the initial beta rollout. Users can now manage five distinct AI modules individually, including translation services, image alt text generation, and AI chatbot providers, giving them granular control over how and when AI is used in the browser. In addition to these privacy-focused enhancements, Firefox 148 introduces several new user experience features, such as split view for improved multitasking, HDR video streaming on Windows, and a redesigned, customizable sidebar. The update also includes security improvements and enhancements to profile management and data collection, further strengthening user privacy and system integrity. These developments reflect Mozilla’s ongoing commitment to user autonomy, transparency, and security in an era of rapidly expanding AI integration in digital platforms.
