Firefox is a fast, full-featured Web browser. It offers great security, privacy, and protection against viruses, spyware, malware, and it can also easily block pop-up windows. The key features that have made Firefox so popular are the simple and effective UI, browser speed and strong security capabilities.
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.
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.
- Dark mode in reader view expands so that windows are also dark on the controls, sidebars and toolbars.

- New reporting feature in about:addons allows you to report security and performance issues with extensions and themes.
- Redesigned extensions dashboard in about:addons provides easy access to information about your extensions, including data and settings access required by each extension.
- Find high quality, secure extensions via the Recommended Extensions program in about:addons, which now displays user count and ratings for each extension. "Recommended” badges for these extensions also appear on AMO. More extensions will be added over time.
- Cryptomining and fingerprinting protections are added to strict content blocking settings in Privacy & Security preferences.
