firefox nova

Firefox Nova is Mozilla's redesigned Firefox interface, covered on WindowsForum.com as it moves toward becoming the desktop default in Firefox 157 on September 29, 2026. The coverage describes softer tabs, refreshed icons, a warmer colour palette, and the return of Compact Mode, along with easier access to tab groups, split view, and vertical tabs. Mozilla indicates extensions, shortcuts, and menus stay where users expect them, framing Nova as the biggest visual change since 2021 but largely a coat of paint rather than a new way of working. Discussion also notes Firefox's continued support for full Manifest V2 uBlock Origin, which Chrome no longer runs.
