Mozilla is working on a major overhaul of its Firefox browser, and, with the general release of Firefox 57 today, has reached a major milestone. The version of the browser coming out today has a sleek new interface and, under the hood, major performance enhancements, with Mozilla claiming that it's as much as twice as fast as it was a year ago. Not only should it be faster to load and render pages, but its user interface should remain quick and responsive even under heavy load with hundreds of tabs.
Collectively, the performance work being done to modernize Firefox is called Project Quantum. We took a closer look at Quantum back when Firefox 57 hit the developer channel in September, but the short version is, Mozilla is rebuilding core parts of the browser, such as how it handles CSS stylesheets, how it draws pages on-screen, and how it uses the GPU.
