Firefox 157 Redesign Introduces Rounded UI and Compact Mode

Redesign Overview
Firefox 157 launches with a visual overhaul that adds bubble-like tabs, a rounded address bar, and refreshed colors, icons, and themes. The update aligns the desktop and mobile browsers under a single design language, and Mozilla asserts that the new look does not affect performance.
Design Details and Customization
The refreshed interface emphasizes softer, rounded UI elements, making Firefox’s appearance more similar to competing browsers. Mozilla also expands personalization, offering a new set of themes and wallpapers and a palette of twelve colors, each provided in light and dark variants.
Compact Mode Returns
User demand has driven the reinstatement of Compact Mode, a condensed layout that shrinks tabs and the toolbar to maximize screen real estate. An auto-compact option automatically applies the tighter spacing on smaller displays, giving users more space for web content.
Mozilla’s Official Position
Mozilla describes the redesign as a “renewal” for Firefox, building on recent major updates such as homepage widgets, Split View, a built-in VPN, AI-feature controls, and the Smart Window AI mode introduced earlier this year. The company emphasizes that the visual changes are intended to modernize the browser while preserving speed and functionality.
