New Firefox quantum browser uses 30% less memory than other browsers

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

Firefox 57 has been a long time in the making.

The browser market may about to become a lot more competitive. Firefox has remained based on an archaic architecture that offers noticeably limited performance next to its contemporaries. The new version of Firefox is now available out of beta for Windows, Mac and Linux, meanwhile the new UI update is also available on Android and iOS. Quantum is a Mozilla project to modernise the core of Firefox that's been in production for over a year.

To achieve a better performance, Firefox Quantum runs on multiple CPU cores on desktop and mobile, rather than just one CPU core like previous versions. It also uses less memory than competing browsers with a fresh new UI in place. "No other browser can do this", Mozilla claims. 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. Menus have been revised, there's a new unified search bar and the sidebar has been reorganised.

Quantum has a new minimal design. This update has taken six months, but the results seem to be paying off.

Beyond that, there are also three variations on the default theme, depending on whether you prefer the inactive tab to be the same color as the titlebar - in the default setting -, a more muted shade of grey, or dark grey, with the last one being particularly suited for work at night. Next year Mozilla will be working to improve these areas. Right now, Chrome boasts a 54.57% market share, while Firefox is languishing at 6.08%. Do many of you now use Firefox?

"What you'll notice first is that the new Firefox is blazing fast", Mozilla wrote on its blog. There's also a Library feature that provides quick access to bookmarks, Pocket, history, downloads, synced tabs, and screenshots.

This move makes Google Mozilla's default search engine in most of the world, with the exception of China, where the default is Baidu, and Russia, Turkey, Belarus and Kazakhstan, where Yandex is the default. If you now rely on a traditional Firefox extension, you may want to hold off on updating until it's been converted to a modern WebExtension.

Of course Firefox still supports extensions and themes.
