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 69.0, first offered to Release channel users on September 3, 2019
As of today, Enhanced Tracking Protection will be turned on by default, strengthening the security and privacy for all of our users around the world. We’d like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox.
Enhanced Tracking Protection (ETP) rolls out stronger privacy protections:
The default standard setting for this feature now blocks third-party tracking cookies and cryptominers.
The optional strict setting blocks fingerprinters as well as the items blocked in the standard setting.
The Block Autoplay feature is enhanced to give users the option to block any video that automatically starts playing, not just those that automatically play with sound.
For our users in the US or using the en-US browser, we are shipping a new “New Tab” page experience that connects you to the best of Pocket’s content.
Support for the Web Authentication HmacSecret extension via Windows Hello now comes with this release, for versions of Windows 10 May 2019 or newer, enabling more passwordless experiences on the web.
Support for receiving multiple video codecs with this release makes it easier for WebRTC conferencing services to mix video from different clients.
For our users on Windows 10, you’ll see performance and UI improvements:
Firefox will give Windows hints to appropriately set content process priority levels, meaning more processor time spent on the tasks you’re actively working on, and less processor time spent on things in the background (with the exception of video and audio playback).
For our existing Windows 10 users, you can easily find and launch Firefox from a shortcut on the Win10 taskbar.
For our users on macOS, battery life and download UI are both improved:
macOS users on dual-graphics-card machines (like MacBook Pro) will switch back to the low-power GPU more aggressively, saving battery life.
Finder on macOS now displays download progress for files being downloaded.
Various security fixes
As previously announced in the Plugin Roadmap for Firefox, the “Always Activate” option for Flash plugin content has been removed. Firefox will now always ask for user permission before activating Flash content on a website.
With the deprecation of Adobe Flash Player, there is no longer a need to identify users on 32-bit version of the Firefox browser on 64-bit version operating systems reducing user agent fingerprinting factors providing greater level of privacy to our users as well as improving the experience of downloading other apps.
Firefox no longer loads userChrome.css or userContent.css by default improving start-up performance. Users who wish to customize Firefox by using these files can set the toolkit.legacyUserProfileCustomizations.stylesheets preference to true to restore this ability.
For Enterprise system administrators that manage macOS computers, we begin shipping a Mozilla signed PKG installer to simplify your deployments.
For our mobile web developers, we have migrated remote debugging from the old WebIDE into a re-designed about:debugging, making debugging GeckoView on remote devices via USB rock solid.
The network panel will now show blocked resources to allow developers to best understand the impact of content blocking and ad blocking extensions given our ongoing expansion of Enhanced Tracking Protection to all users with this release.
The new event listener breakpoint feature allows developers to pause on a host of different event types, whether it be related to animations, DOM, media, mouse, touch, worker, and many other event types.
Firefox Developer Tools now offers an audit for the presence of text alternatives for non-text content, the a11y panel checks toolbar has been augmented to better help developers adhere to WCAG Guideline 1.1.
