Mozilla has released the beta version of 57th version of the proprietary Firefox browser. This is such a large and important update that the developers even gave it the name - Firefox Quantum. In the Speedometer 2.0 benchmark, which compares modern web apps, Firefox Quantum was about twice as fast as Firefox 52, released about a year ago. According to the official website of Mozilla, Firefox initially worked with only one CPU core, but with the release of Firefox Quantum, the browser learned how to interact with several cores on desktops and mobile devices, which brings significant performance benefits.
Firefox Quantum uses a new CSS engine written in Rust that works in parallel with multiple cores. According to developers, no other browser can do this. Mozilla also optimized Firefox to give the main priority to the tab that you are currently viewing. This, along with the new multiprocessor architecture, provides greater performance and at the same time a 30% lower consumption of RAM.
In addition to the changes under the hood, the developers also revised the browser's user interface. In the new version of Firefox, the user interface is called Photon, which offers a minimalistic and adaptive design. For example, if you are using a Windows computer with a touchscreen, the Firefox menu will change the size based on whether you use the mouse or the touchpad. Photon also includes square tabs, smooth animations and a library where you will find the saved content, including downloaded files and screenshots.
Browser is available in beta at the moment, final release is planned on the 14th November.
