Mozilla officially launched the Firefox 69 web browser earlier this week with several new privacy and security features, such as the enablement of the Enhanced Tracking Protection by default to automatically block cryptominers, fingerprinters, and third-party tracking cookies. Firefox 69 also introduces a new Block Autoplay feature to automatically block video content from automatically playing, improves support for WebRTC conferencing services, and brings JIT support to ARM64 systems to improve the performance of Mozilla’s JavaScript Optimizing JIT compiler.
