Firefox on macOS: TouchID, Apple Silicon, and Platform-Specific Features
Firefox on macOS has some specific integrations worth knowing about, plus a few rough edges compared to Safari. TouchID for Passwords Firefox on macOS supports TouchID for the built-in password manager.

Firefox on macOS offers several integrations and features tailored to the platform, but also has some differences compared to Safari. One notable feature is TouchID for Passwords, which allows Firefox to prompt for TouchID (or the user's login password) when autofilling saved passwords instead of revealing them directly. To enable this, users can go to Settings → Privacy & Security → Passwords and check the box for "Use Touch ID".
Another integration is with the System Keychain. Firefox stores passwords in its own format, separate from the macOS Keychain, which means they don't sync with Safari or appear in Keychain Access. For those who want their Firefox passwords in the system keychain, they'll need to use third-party password managers like Bitwarden or 1Password that work with both Firefox and the system keychain.
Firefox also supports Retina displays natively, rendering at Retina resolution without any blurriness. Users can verify this by checking the Graphics section in about:support; the Device Pixel Ratio should show 2.0 on Retina displays. If it's showing 1.0, Firefox may not be running in Retina mode, which can be corrected by adjusting display settings.
Performance on Apple Silicon (M1, M2, M3) chips is notably better with Firefox, thanks to its native ARM64 build. Users should ensure they're running the native ARM version, not the Intel-compiled Rosetta version. This can be confirmed by right-clicking Firefox in the Finder → Get Info, and checking the "Kind" field. If it says "Application (Apple silicon)," users have the native version. The Apple Silicon build provides better performance and battery life compared to the Rosetta translation.
Firefox follows macOS's permission model for hardware access. The camera and microphone are prompted per site, as is the location permission, which can be denied globally. The downloads folder is also granted access by default, but users can manage this in System Settings → Privacy & Security → Files and Folders. Additionally, Firefox respects macOS's dark mode, switching between light and dark themes automatically based on the system setting. Users can also adjust this on a per-site basis in Settings → Extensions & Themes.
Spotlight integration allows Firefox history and bookmarks to be searchable via Spotlight if Firefox is set as the default browser. Users can set Firefox as the default browser via Settings → General → Make Firefox your default browser. Firefox notifications also appear in the macOS Notification Center for sites with notification permission.
Users can manage these permissions via Settings → Privacy & Security → Permissions → Notifications. Firefox uses macOS's built-in spell check for form fields and contenteditable elements, and users can add words to the dictionary by right-clicking a misspelled word and selecting "Learn Spelling". Two-finger swipe gestures for back/forward navigation are supported on Macs with trackpads by default.
If this feature isn't working, users can enable it via System Settings → Trackpad → More Gestures → Swipe between pages.
