Firefox Quantum Developer Edition: the fastest Firefox ever with Photon UI and better tooling

Firefox Quantum Developer Edition: the most wonderful Firefox ever with Photon UI and better tooling

Firefox Quantum is now available in Developer Edition, and this Firefox is fast.

As a reader of the Hacks blog, you may be familiar with Project Quantum, our attempt to refactor, redesign, replace, and modernize the very core of Firefox. Weave shipped many incremental improvements to Firefox in the past, but this release marks the first milestone which is something we believe Firefox fundamentally feels like a newer, better browser.

To celebrate, we dedicated Developer Edition a brand new logo 😛 TAGEND

Why does this feel like a brand new browser? Read on!

Firefox Quantum: Towards a next-gen browser

Developer Edition now includes aQuantum CSS, a an entirely new CSS engine written in Rust and based on the Servo parallel browser engine project. Additionally, the aQuantum Flowa team tracked down and fixed 369 performance glitches in Firefox, with a special focus on responsiveness and UI interactions. Lastly, the” Quantum DOM” project began overhauling how Firefox prioritizes run, reacting more quickly to events like user input while delaying less urgent computations until the browser is idle.

The result? Compared to Firefox six months ago, todayas Developer Edition is twice as fast on benchmarks like Speedometer 2.0 that simulate the real-world performance of modern web applications.

Furthermore, Firefox is 64 -bit and multi-process by default, and Firefoxas unique architecture allows it to take advantage of modern, multi-core processors while still respecting your available RAM. Meanwhile, the aQuantum Compositora project significantly reduced accidents caused by buggy graphics drivers.

Photon: Firefoxas new UI

To complement Quantum, the Photon team rebuilt Firefoxas interface to be faster and more modern 😛 TAGEND

Youall hear more about Photon in November, but highlightings include redesigned menus, square tabs, and a new aLibrarya button that acts as a single place for your bookmarks, downloads, history, etc. By default, Photon blends the search and URL bars into a single widget, but the old style is merely a predilection away.

The aActivity Streama project redesigned the New Tab Page to feature highlightings from your recent history and bookmarks, as well as recommendations from Pocket. Of course, each of these content blocks are optional, and add-ons can totally replace the new tab page to create entirely different experiences.

We also refreshed form handle in Firefox, adding a brand new autofill feature and enforcing built-in widgets for and elements.

Lastly, Firefoxas preferences were completely redesigned and are now searchable.

DevTools in 57: Redesigned and better than ever

Firefox Quantum: Developer Edition also includes a ton of refined, redesigned, and brand new developer tools.

A few highlightings 😛 TAGEND The Console, Debugger, and Network tabs are now implemented use standard web technologies, including React and Redux, as part of our “devtools.html” endeavour. The Inspector gained tons of new features for working with CSS Grid, CSS Variables, toggling class on components, etc. The Console now supports grouping messages and expanding/ inspecting objects in-line. The Debugger offers completely new ways to search, navigate, and debug projects.
