Compatibility Overview
Mozilla Firefox runs natively on macOS Sonoma through a Universal Binary supporting both Intel and Apple Silicon architectures. Firefox uses its own Gecko rendering engine and WebRender compositor, providing an independent browser experience from the Chromium ecosystem.
Firefox integrates with macOS Sonoma’s notification center and respects Focus mode settings. The browser uses its own password management and syncing through Firefox accounts rather than integrating with macOS Keychain or iCloud.
