Mozilla gives Firefox AI Runtime a big speed boost with native C++
Mozilla engineers have accelerated the Firefox AI Runtime by replacing its WebAssembly-based backend with a native C++ ONNX Runtime implementation. This architectural shift has yielded performance gains of 2-10 times for on-device machine learning features, eliminating WASM warm-up overhead and using hardware-specific CPU instructions for faster model execution. Mozilla explains the WASM bottleneck it faced …
