Powered by a new, cutting-edge engine, Firefox has doubled its speed from last year. Because the Internet waits for no one.
Lean, mean speed machine

Project Quantum, our effort to create a next-generation engine. Firefox 57 includes many aspects of this project, so we’re calling this release Firefox Quantum.
Firefox Quantum is roughly 2X faster than Firefox 49 on the Speedometer 2.0 benchmark, thanks to its new CSS engine, its “just right” multi-process architecture, the way it prioritizes your active tab, and much more. Firefox Quantum also includes a visual refresh – Photon – that looks and feels right at home with modern operating systems. To learn more about Firefox Quantum, visit the Mozilla Blog.
