Mozilla improves the Firefox browser with a new graphics rendering technology

Mozilla released its Firefox 53 update on April 19, introducing a new browser engine and patching 39 vulnerabilities in the open-source web browser.

The new browser engine technology in Firefox 53 is known as Project Quantum and is a multipart effort to accelerate and improve the web browsing experience for users. The Project Quantum component included in Firefox 53 is known as the Quantum Compositor; it is designed to help reduce the number of browser crashes due to graphics issues.

With the Quantum Compositor, graphics rendering is now done separately from the main Firefox process. Mozilla’s early testing for the Quantum Compositor found that it reduces the number of browser crashes by 10 percent.

“The compositor determines what you see on your screen by flattening into one image all the layers of graphics that the browser computes, kind of like how Photoshop combines layers,” Nick Nguyen, vice president for Firefox at Mozilla, wrote in a blog post.

Firefox 53 also introduces two new user interface themes. The Compact Light theme provides users with a more compact, smaller user interface using the default Firefox color scheme. The Compact Dark theme also has a compact user interface, but it provides a darker color scheme for night browsing.
