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.

Version 59.0, first offered to Release channel users on March 13, 2018
If you’re a regular reader of Firefox release notes (and thank you if you are!) you’re probably aware of just how much we’ve invested in the performance of Firefox Quantum. We launched an entirely new engine in November, made significant improvements to graphics rendering in January, and are continuing to post performance gains and add features with this release. On Firefox for desktop, we’ve improved page load times, added tools to annotate and crop your Firefox Screenshots, and made it easier to arrange your Top Sites on the Firefox Home page. On Firefox for Android, we’ve added support for sites that stream video using the HLS protocol.
As always, this is made possible by Mozillians around the world, including the new Mozillians who contributed to this release of Firefox.
– Faster load times for content on the Firefox Home page
– Faster page load times by loading either from the networked cache or the cache on the user’s hard drive (Race Cache With Network)
– Improved graphics rendering using Off-Main-Thread Painting (OMTP) for Mac users (OMTP for Windows was released in Firefox 58)
Drag-and-drop to rearrange Top Sites on the Firefox Home page, and customize new windows and tabs in other ways

Added settings in about:preferences to stop websites from asking to send notifications or access your device’s camera, microphone, and location, while still allowing trusted websites to use these features
Various security fixes
Firefox Private Browsing Mode will remove path information from referrers to prevent cross-site tracking
Windows 7 users using accessibility services (like the Windows On-Screen Keyboard) may observe browser crashes after the update to Firefox 59. As a workaround, affected users can prevent external apps from triggering accessibility services in Firefox.
