Engines are important, both in cars and in browsers. That\u2019s why we\u2019re so revved up this morning \u2013 we\u2019re releasing the Beta of a whole new Firefox, one that\u2019s powered by a completely reinvented, modernized engine. Since the version number \u2013 57 \u2013 can\u2019t really convey the magnitude of the changes we\u2019ve made, and how much faster this new Firefox is, we\u2019re calling this upcoming release Firefox Quantum<\/a>.<\/p>\n

The journey to Firefox Quantum<\/b><\/h3>\n

Last October we announced Project Quantum<\/a>, our effort to create a next-generation engine for modern computers, by leveraging technology from our Servo research project<\/a>. Since then, our engineering team has been relentless in their focus on making Firefox incredibly fast.<\/p>\n

Already this year we\u2019ve launched several major improvements to Firefox that have it made it better than ever. For example, we\u2019ve transformed Firefox to run using multiple processes, striking the \u201cjust right\u201d balance between speed and memory usage<\/a>. In addition, we\u2019ve launched game-changing features like WebAssembly<\/a> and WebVR<\/a>, enabling super fast, near-native performance for web apps on the desktop and on VR headsets.<\/p>\n

We\u2019ve shipped a lot already, but we\u2019ve been planning for many more projects to come together in Firefox Quantum.<\/p>\n

<\/h2>\n

Noticeably faster on many of the top websites<\/b><\/h3>\n

Firefox Quantum is such a big leap forward that you\u2019ll feel it instantly, just browsing your favorite websites.<\/p>\n

Turns out you can measure Firefox Quantum\u2019s speed, too \u2013 our pit crew is kind of obsessed with a data-driven approach<\/a>. One simple way of estimating browser performance is with Speedometer 2.0<\/a>, a (still-in-development) benchmark that simulates modern web applications. Results vary based on the computer and apps you\u2019re actively using, but one thing that\u2019s relatively consistent is that Firefox Quantum is about 2X faster<\/a> than Firefox was a year ago.<\/p>\n

We encourage you to make your own comparisons, but here\u2019s a short video that captures our observations when comparing Firefox Quantum and Chrome on various websites. Firefox Quantum is often perceivably faster.<\/p>\n
