Firefox 157 swaps its interface for a new visual language

Firefox 157 has reinvented its interface with new colors and icons. The update includes a compact mode and hardware AV1 support.

Compact mode reduces the use of screen space and lets users organize shortcuts on the home screen. Hardware AV1 decoding improves playback of 8-bit HDR videos. The reorganization of the settings menu makes it easier to access privacy controls and allows users to disable AI in bulk. The browser is available for Windows, macOS, Linux, Android and iOS with version 157. The visual overhaul of Firefox 157 represents one of the biggest updates in years, with the intention of competing with browsers such as Chrome and Edge.
