The “Activity Stream” project redesigned the New Tab Page to feature highlights from your recent history and bookmarks, as well as recommendations from Pocket. By default, Photon combines the search and URL bars into a single widget, but the old style is only a preference away.

You’ll hear more about Photon in November, but highlights include redesigned menus, square tabs, and a new “Library” button that acts as a single place for your bookmarks, downloads, history, etc. To complement Quantum, the Photon team rebuilt Firefox’s interface to be faster and more modern: Meanwhile, the “Quantum Compositor” project significantly reduced crashes caused by buggy graphics drivers. The result? Compared to Firefox six months ago, today’s Developer Edition is twice as fast on benchmarks like Speedometer 2.0 that simulate the real-world performance of modern web applications.įurthermore, Firefox is 64-bit and multi-process by default, and Firefox’s unique architecture allows it to take advantage of modern, multi-core processors while still respecting your available RAM. Lastly, the “Quantum DOM” project began overhauling how Firefox prioritizes work, responding more quickly to events like user input while delaying less urgent computations until the browser is idle. Additionally, the “Quantum Flow” team tracked down and fixed 369 performance bugs in Firefox, with a special focus on responsiveness and UI interactions. Why does this feel like a brand new browser? Read on! Firefox Quantum: Towards a next-gen browserĭeveloper Edition now includes “Quantum CSS,” an entirely new CSS engine written in Rust and based on the Servo parallel browser engine project.

To celebrate, we gave Developer Edition a brand new logo: We’ve shipped many incremental improvements to Firefox in the past, but this release marks the first milestone where we believe Firefox fundamentally feels like a newer, better browser.
