Apple's iCloud Passwords extension adds support for Firefox

Apple's iCloud Passwords extension now supports Firefox. It's about time.

The Chrome/Edge version of the add-on debuted in 2023, but the Firefox version launched last December. Back then, I had noted that it does not support Firefox on Windows, Linux, or older versions of macOS other than Sonoma. It was, for some reason, a macOS exclusive until now.

About 7 months later, the Cupertino company has decided to add support for Mozilla's browser out of the blue. Now, there is a good chance that it may not work for you, and you see a message that says "The Passwords extension is not currently available on Firefox for Windows. It is available in Chrome and Edge."

Some people are speculating that this is because Apple has not updated the extension since February 2025. The iCloud app for Windows has been updated recently (I must have missed it), and the release notes mentions that "The iCloud Passwords extension is now available for Firefox".

Some users claim that it must require Windows 11, i.e., it is not compatible with Widows 10, and that's why the add-on doesn't work. While I don't know about the Windows 10 part, I can tell you the extension works on Windows 11. There are 2 possible reasons why you are getting this error. One, is because you don't have the latest version of the iCloud for Windows app installed on your PC. You can download it from the Microsoft Store.The other reason why the add-on is not working could be because your Firefox was open before you installed the Windows app, and it is not recognizing the app. All you need to do is restart the browser.

Try clicking on the extension's button again, and iCloud Passwords should now work. It will ask you to verify the process by entering a number that is displayed by the Windows app, in order to start syncing your passwords. Do so, and you will be able to access and manage your Apple Passwords on Firefox for Windows, and use it to autofill your passwords on login forms.

It's not supported on Linux, since the iCloud app isn't available for Linux.
