Dark Theme Darkening: Better Theming for Firefox Quantum
A team of computer science students from Michigan State University's capstone program went to work on Firefox Quantum’s Theming API. Their goal: Expand upon the existing “lightweight” Theming API in Quantum to allow for more areas of customization. Themes had the ability to alter the appearance of the default toolbars, but did not have the ability to style menus, or customize auto-complete popups -- till now. The team also worked on adding a more fluid transition when dynamic themes change, to allow for a smoother user experience.

Firefox 61 – Quantum of Solstice
Firefox 61 is now available, bringing new performance improvements that make the fox faster than ever! We're keen on the Retained Display Lists feature to improve performance while an interactive page is painted; the Accessibility Inspector baked in to our tooling to support assistive technology users; more powerful tab management for power users; and many more Dev Tools updates and enhancements.

Retained Display Lists for improved page performance
Display list building is the process in which we collect the set of high-level items to display on screen (borders, backgrounds, text and much more), and then sort the list, according to CSS painting rules, into the correct back-to-front order. By retaining the display list and only reloading the assets that have changed since first paint, we are able to optimize painting performance especially for highly interactive pages. Look for this feature in this week's release of Firefox 61.
