Introducing the New Firefox: Firefox Quantum

It’s fast. Really fast.Firefox Quantum is over twice as fast as Firefox from 6 months ago, built on a completely overhauled core engine with brand new technology stolen from our advanced research group and graced with a beautiful new look designed to get out of the way and let you do what you do best.

It’s by far the biggest update we’ve had since we launched Firefox 1.0 in 2004, it’s just flat out better in every way.If you go and install it right now.The first thing you’ll notice is the speed.Go on, open some tabs and have some fun.The second thing you’ll notice is the new User Interface (UI).Our user research team studied how people browsed the web.

We looked at real world hardware to make Firefox look great on any display.We made many, many performance improvements in the browser’s core and shipped a new CSS engine, Stylo, that takes better advantage of today’s hardware with multiple cores that are optimized for low power consumption.

Making Firefox look, feel and perform faster.Check out the new Firefox browser on Windows, Mac or Linux. The new appearance will also be available on iOS and Android.
