Mozilla is rolling out a major Firefox redesign codenamed Project Nova, focused on making the browser feel cleaner, warmer, and faster. Key changes include updated tab shapes with subtle gradients, a refreshed color palette inspired by fire, more rounded and consistent UI components, rebalanced spacing, and updated icons. Privacy features are being surfaced more prominently, including easier access to the built-in VPN, private browsing, and redesigned Settings with plainer language. Performance improvements include a 9% reduction in key page content load times. Productivity features like tab groups, split view, and vertical tabs are more accessible, and compact mode is returning by popular demand. The redesign extends to mobile for cross-device consistency, and new themes and wallpapers are being added. Accessibility — contrast, readability, keyboard behavior, and dark mode — is a core design consideration throughout.
