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 65.0, first offered to Release channel users on January 29, 2019
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: Simplified content blocking settings give users standard, strict, and custom options to control online trackers. A redesigned content blocking section in the site information panel (viewed by expanding the small “i” icon in the address bar) shows what Firefox detects and blocks on each website you visit. To learn more about content blocking, visit the Mozilla Blog.
A better experience for multilingual users: An updated Language section in Preferences allows users to install multiple language packs and order language preferences for Firefox and websites, without having to download locale-specific versions.
Support for Handoff on macOS: Continue browsing across devices. Pick up where you left off with iOS (via Firefox or Safari) on Firefox on Mac.
A better video streaming experience for Windows users: Firefox now supports the next-generation, royalty-free video compression technology called AV1. Read about Mozilla’s contribution to this new open standard.
Improved performance and web compatibility, with support for the WebP image format: WebP brings the same image quality as existing formats at smaller file sizes, which saves bandwidth and speeds up page load.
Various security fixes
Enhanced security for macOS, Linux, and Android users via stronger stack smashing protection which is now enabled by default for all platforms. “Stack smashing” is a common security attack in which malicious actors corrupt or take control of a vulnerable program.
Firefox will now warn you when closing a window (regardless of whether you have automatic session restore enabled for restart).
Easier performance management: The revamped Task Manager page found at about:performance now reports memory usage for tabs and add-ons.
Improved the pop-up blocker to prevent multiple pop-up windows from being opened by websites at the same time.
Firefox for Windows is now available with 32- and 64-bit MSI installers for easier enterprise deployments.
Additional support for Flexbox: Launched a new Flexbox inspector tool that details Flexbox containers and helps debug Flex item sizes.
All CSS changes made in the Rules panel are now tracked in the new Changes tab.
Added support for the Storage Access API on desktop platforms.
