Firefox Is Getting a Major Redesign After 5 Years

Mozilla is internally working on a major Firefox UI redesign codenamed "Nova," leaked by developer Sören Hentzschel. The redesign moves away from the flat Proton design (in use since 2021) toward a more modern look featuring rounded corners throughout, a floating unified toolbar island, subtle gradients, violet color accents, and a redesigned browser menu. Mockups show dark mode with split-view, light mode with tab groups as colored pills, and a visually distinct dark-purple private browsing window. No official announcement has been made yet, but Mozilla's Bugzilla has active entries tracking Nova's development.
