Mozilla Firefox is a fast, full-featured Web browser. Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.
Quantum is Mozilla’s project to build the next-generation web engine for Firefox users, building on the Gecko engine as a solid foundation. Quantum will leverage the fearless concurrency of Rust and high-performance components of Servo to bring more parallelization and GPU offloading to Firefox.
Firefox (Quantum) users will be impressed by the modern new design that puts their needs first. With the new (fast and fluid Photon) design, Firefox leaps ahead with a new interface that reflects today’s reality of High DPI displays and users who are more task focused than they’ve ever been. Photon doesn’t just look good, it’s also smarter. 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, minimalist design introduces square tabs, smooth animations, and a Library, which provides quick access to your saved stuff: bookmarks, Pocket, history, downloads, tabs, and screenshots. Firefox Quantum feels right at home with today’s mouse and touch-driven operating systems: Windows 10, macOS High Sierra, Android Oreo, and iOS 11.
Firefox has historically run mostly on just one CPU core, but 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.
Firefox Quantum enhances Firefox’s integration with Pocket, the read-it-later app that Mozilla acquired last year. When you open a new tab, you’ll see currently trending web pages recommended by Pocket users so you won’t miss out on what’s hot online, as well as your top sites.
A focus on privacy brings an option to turn on tracking protection, which blocks known tracking scripts, at all times, not just in private browsing mode. Protection against HTML5 canvas fingerprinting – another way that users can be tracked around the internet – will be released in v58, This is a feature borrowed from Tor Browser.
Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.
