Mozilla unveiled a major visual and functional overhaul of Firefox on Wednesday, the browser's largest redesign since 2020, with changes to its appearance, privacy settings, and AI controls expected to roll out later this year.
Across desktop and mobile, the initiative — known inside Mozilla as Project Nova — encompasses changes to tabs, icons, spacing, color choices, and settings. Tab shapes are becoming rounder and softer, with a gradient effect lending the active tab greater visual prominence; the surrounding interface — including menus, panels, and controls — is being brought into alignment for a unified feel. For color, Mozilla drew inspiration from fire, moving away from flatter hues toward a combination of deep smoky purples and warmer, lighter shades.
Privacy tools are also getting attention, with the Settings menu being reworked so that data controls are simpler to locate and interpret. Built-in VPN access and private browsing options will occupy a more visible position within the interface, and a dedicated kill switch will let users shut off all AI-related functionality if they choose. The language used to describe Enhanced Tracking Protection options is being simplified to make the tradeoffs between privacy and usability easier to grasp.
