Firefox rolls out its new modern design to all users with version 157. The update brings a refreshed visual language across desktop and mobile, featuring new colors, icons, and themes while maintaining the browser's core privacy focus. The design ethos aims to feel "current, but not generic, warm, but still precise." Key additions include the return of Compact Mode to reduce tab size and reclaim screen space, a new theme picker with custom wallpapers, and enhanced New Tab page customization options.

Firefox remains independent and open source, with privacy protections built-in and user controls over AI features. The redesign carries forward the same principles that have shaped Firefox from the beginning, offering a consistent foundation for future features. Users can explore different looks and set up their homepage with pinned shortcuts for frequently used sites.

The update represents a renewal grounded in Firefox's founding principles, with a fresh aesthetic designed to carry the browser forward while preserving its unique personality.
