Firefox's faster, slicker, slimmer Quantum edition now out

Firefox Quantum 57 Is Here To Kill Google Chrome: Download For Windows, Mac, Linux

Firefox Quantum arrives with faster browser engine, major visual overhaul, and Google as default search engine

In a browser speed test video that Mozilla posted to the site, the new Firefox beat out Chrome in loading a few big name websites like Yelp and Shutterstock as well.

Mozilla has officially launched the fastest version of its Firefox browser yet.

Lastly, there is one major caveat: starting with Firefox 57, the browser will only support those addons which are built either from the ground up or adapted to use the WebExtensions API. But with this Firefox Quantum update, Google will now be the default search provider for everyone in the United States and Canada - unless the end user changes said default, that is.

Mozilla's engineers totally rebuilt the core engine, giving it brand new "guts", and interacting with 7 million lines of code in the process.

Firefox is free, as it's always been, and it can be downloaded by anyone with a desktop computer right now from Mozilla. That performance increase is complemented by an architecture upgrade that, according to the company, uses 30% less memory than Google Chrome. This lower memory footprint is most noticeable when opening multiple tabs (which all of us frequently do), as users won't see a drag on performance or crippling memory and CPU usage that can often cripple Chrome. Mozilla has also fixed hundreds of issues related to Firefox slowness in the past several months, adding to the feeling of a faster browser. Indeed, three of the four past releases (Firefox 53, Firefox 54, and Firefox 55) included Quantum improvements. Mozilla is determined to win you back.

"You should feel good about using Firefox because it contributes to Mozilla which contributes to a healthy internet", said. Mozilla's also extensively updated the browser engine, the internal components responsible for displaying webpages, applying styles and handling interactive elements.

"We call this initiative Photon, and its goal is to modernize and unify anything that we call Firefox while taking advantage of the speedy new engine", the team explained. You can expect square tabs, a dark color scheme, smooth animations, and a restructuring of menus. Firefox 57 also includes an inbuilt tool to take screenshots.
