It doesn't mean that today's Firefox is as fast and responsive as it's going to be. It offers great security, privacy, and protection against viruses, spyware, malware, and it can also easily block pop-up windows.
The Quantum name signals Firefox 57 is a huge release that incorporates the company's next-generation browser engine (Project Quantum). To take advantage of its syncing features that ensure you can access your Firefox browsing history and other preferences on its iOS and Android apps, as you do with your Google account, you'll need a Firefox Account.
Firefox today released its newest browser Firefox Quantum out of beta. Quantum will leverage the fearless concurrency of Rust and high-performance components of Servo to bring more parallelization and GPU offloading to Firefox. The new UI is optimized for High DPI and touchscreen displays. Photon doesn't just look good, it's also smarter. If you use Quantum 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.
"Firefox Quantum is over twice as fast as Firefox from 6 months ago, built on a completely overhauled core engine with brand new technology stolen from our advanced research group, and graced with a attractive new look created to get out of the way and let you do what you do best: surf a ton of pages, open a zillion tabs, all guilt free because Firefox Quantum uses less memory than the competition", boasts Mozilla senior vice president Mark Mayo. This improved utilization of your computer's hardware makes Firefox Quantum dramatically faster.
You can set one up right when you open Firefox Quantum.
The first ever Quantum-fueled Firefox version, Firefox 57, is about to land on your Windows, Linux, and macOS machines. The new browser also includes Pocket recommendations of what sites to browse on every new tab.
