Of course, the browser isn't yet available to consumers, so there's no third-party data to substantiate Mozilla's claims. Mozilla is still working on a new GPU-optimized rendering engine that could clearly put Firefox ahead of other browsers in terms of performance.
The key advantage of Firefox over Quantum as the eponymous predecessor, and over its closest competitors, is more sparing use of browser memory. And this isn't your average browser; the beta version which is now available is twice as fast as the current Firefox browser and uses 33% less energy than Google's Chrome.
Firefox Quantum will test whether Mozilla's efforts to modernize its browser can pay off.
"Firefox Quantum is about 2X faster than Firefox was a year ago", he said, citing the Speedometer 2.0 benchmark, and comparing Quantum to March's Firefox 52. That's why, 15 years ago, Mozilla began a project initially called Phoenix to start over and in 2004 released Firefox 1.0.
Now a beta release, Firefox Quantum has a new Rust-based CSS engine that can take advantage of multicore processors.More news: Netanyahu praises work of IDF rescue team in Mexico

Firefox has historically run mostly on just one CPU core, but Firefox Quantum takes advantage of multiple CPU cores in today's desktop and mobile devices much more effectively.
Last but not least, Mozilla has fixed 468 issues related to Firefox slowness in the past several months, adding to the feeling of a faster browser. Overall, it's got a more minimalist look, which will work well on high-DPI displays, but die-hard fans of the original style can still switch back to old familiar via preferences.
Pocket users will be happy to know that Firefox Quantum has a built-in Pocket bookmarking service. If you're using Photon on a Windows PC with a touch display, the menus change size based on whether you click with a mouse or touch with a finger.
The new Firefox revamps includes lots of under-the-covers improvements like Quantum Flow, which stamps out dozens of performance bugs and Quantum CSS, aka Stylo, which speeds up website formatting. You can expect square tabs, smooth animations, and a Library that provides quick access to bookmarks, Pocket, history, downloads, tabs, and screenshots. However, you can try it in Beta on desktop. The UI and user experience (UX) changes, derived from an ongoing project tapped as "Photon", also emphasize speed improvements, both real and simply perceived.
Right now, Firefox 57 - set for release on November 14 - looks like a groundbreaking and highly anticipated release.
