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.

Version 82.0, first offered to Release channel users on October 20, 2020
We’d like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox.
Firefox 83.0 release notes:
Firefox introduces HTTPS-Only Mode. When enabled, this new mode ensures that every connection Firefox makes to the web is secure and alerts you when a secure connection is not available. You can enable it in Firefox Preferences.
Pinch zooming will now be supported for our users with Windows touchscreen devices and touchpads on Mac devices. Firefox users may now use pinch to zoom on touch-capable devices to zoom in and out of webpages.
Picture-in-Picture now supports keyboard shortcuts for fast forwarding and rewinding videos: use the arrow keys to move forward and back 15 seconds, along with volume controls. For a list of supported commands see Support Mozilla
When you are presenting your screen on a video conference in Firefox, you will see our improved user interface that makes it clearer which devices or displays are being shared.
We’ve improved functionality and design for a number of Firefox search features:
Selecting a search engine at the bottom of the search panel now enters search mode for that engine, allowing you to see suggestions (if available) for your search terms. The old behavior (immediately performing a search) is available with a shift-click.
When Firefox autocompletes the URL of one of your search engines, you can now search with that engine directly in the address bar by selecting the shortcut in the address bar results.
We’ve added buttons at the bottom of the search panel to allow you to search your bookmarks, open tabs, and history.
Firefox supports AcroForm, which will allow you to fill in, print, and save supported PDF forms and the PDF viewer also has a new fresh look.
Our users in India on the English build of Firefox will now see Pocket recommendations in their new tab featuring some of the best stories on the web. If you don’t see them, you can turn on Pocket articles in your new tab by following these steps.
For the recently released Apple devices built with Apple Silicon CPUs, you can use Firefox 83 and future releases without any change. This release (83) will support emulation under Apple’s Rosetta 2 that ships with macOS Big Sur. We are working toward Firefox being natively-compiled for these CPUs in a future release.
This is a major release for WebRender as we roll out to more Firefox users on Windows 7 and 8 as well as on macOS 10.12 to 10.15.
Screen reader features which report paragraphs now correctly report paragraphs instead of lines in Google Docs
When reading by word using a screen reader, words are now correctly reported when there is punctuation nearby
The arrow keys now work correctly after tabbing in the picture-in-picture window
For users on macOS restoring a session with minimized windows, Firefox now uses much less power and you should see much longer battery life.
Various security fixes
Developers can use the scroll badge in the Page Inspector to Debug scrollable overflow. Selecting the badge highlights elements that are causing overflow and marks them with the overflow badge
This release adds support for conic gradients in CSS, helping colors to smoothly transition as you spin around the center, rather than as you progress outward from the center.
