Mozilla has officially released Firefox 157, bringing the most significant interface update in recent years to this open-source browser, along with multiple optimizations in video calling, HDR display, and media playback experience. The most eye-catching feature of this update is the all-new 'Nova' interface, which Mozilla describes as the most extensive visual upgrade to Firefox in years. The new design modernizes the browser's top frame, sidebar, and menu system, resulting in a more unified overall style and further optimized visual hierarchy and user experience.
