Firefox Quantum Lands in Beta, Developer Edition
 

Mozilla has released the first beta versions of Firefox 57 that come with a new user interface ("Photon") and a new core engine ("Quantum"): they claim that it is twice as fast as Firefox 52, the version released a year ago. A video demonstrates how Firefox Quantum is often "perceivably faster" than Chrome. 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. This improved utilization of your computer's hardware makes Firefox Quantum dramatically faster. One example: we've developed a breakthrough approach to laying out pages: a super-fast CSS engine written in Rust, a systems programming language that Mozilla pioneered. Firefox's new CSS engine runs quickly, in parallel across multiple CPU cores, instead of running in one slower sequence on a single core. No other browser can do this.
