Firefox Quantum is the result of a years-long effort to dramatically reinvent the quintessential open source browser. The browser is an all-new, cutting-edge engine made to harness the power of todays multi-core computers. With Firefox Quantum, users can open numerous tabs to run web apps, while still having enough RAM available to run traditional desktop apps like Microsoft Word and Adobe Photoshop. Firefox Quantum uses an algorithm written in Rust to match CSS to HTML. This breakthrough algorithm runs super fast, in parallel across multiple CPU cores instead of in a sequence on one CPU core.”]
