iCloud Passwords

iCloud Passwords lets you fill passwords from iCloud Keychain when signing in to websites using Firefox.

The iCloud Passwords Chrome extension allows you to securely autofill passwords stored in your iCloud Keychain when signing into websites using Firefox. It not only fills existing passwords but also saves any new passwords you create directly to your iCloud Keychain, ensuring seamless synchronization across all your Apple devices. Additionally, the extension supports generating verification codes by right-clicking on QR codes, enhancing your two-factor authentication process.

Designed exclusively for macOS Sonoma or later, iCloud Passwords offers a smooth and secure password management experience for Firefox users within the Apple ecosystem. Note that it is currently unavailable for Windows users.

User reviews

Users report that while the add-on can fill passwords, it suffers from major drawbacks: it severely slows down Firefox performance, particularly after macOS 15.4 update. The extension is not functional on Windows or Zen Browser and exhibits poor password memory and syncing across devices. Many users experienced the add-on becoming non-functional after recent OS updates, making it unreliable across platforms.
Pros

  • Does not work or is incompatible on Windows operating system
  • Stopped functioning or breaks after recent macOS (Sequoia 15.4) update
  • Does not work on Zen Browser and possibly other open-source browsers
  • Fails to remember passwords properly and has poor cross-device functionality
