System specifications:
- OS: Windows 11 Pro 26H2
- OS Build: 26300.9818
- iCloud for Windows: 15.10.39.0
- Firefox: 159.0.1
- iCloud Passwords Extension: 3.4.0 (also tested 3.3.0)
Description:
I am experiencing a persistent issue with the iCloud Passwords browser extension on Windows.
Whenever I open the extension in Firefox, it displays:
"Enable Passwords in iCloud for Windows to use iCloud Passwords in Firefox"
However, Passwords & Keychain is already enabled in iCloud for Windows.
The standalone iCloud Passwords application works perfectly and displays all my saved passwords.
Browsers affected:
- Firefox — same error
- Google Chrome — same error
- Microsoft Edge — same error
- Brave — same error
Troubleshooting performed:
I have already tried:
- Restarting Windows, browsers and iCloud for Windows.
- Updating Windows, Firefox and iCloud.
- Using Repair and Reset for iCloud for Windows.
- Signing out and back into my Apple Account.
- Disabling and re-enabling Passwords & Keychain.
- Reinstalling the browser extensions.
- Testing extension versions 3.4.0 and 3.3.0.
- Testing in a separate local Windows account.
- Temporarily disabling Windows Firewall.
- Testing with Bluetooth enabled and my iPhone nearby.
- Reinstalling and resetting iCloud for Windows.
None of these steps resolved the problem.
Additional technical findings:
I checked the Windows Native Messaging configuration:
- The Apple Native Messaging registry entry exists.
- The Firefox JSON manifest exists and is valid.
- iCloudPasswordsExtensionHelper.exe exists and has a valid digital signature.
- Firefox successfully launches iCloudPasswordsExtensionHelper.exe when the extension is opened.
The iCloud logs also contain these errors:
SecAOSKit::getLoggedInUser — Failed to retrieve logged in user
LoadMIDFromKCConfig — Failed to retrieve state
The specified item could not be found in the keychain (-25300)
Interestingly, the standalone iCloud Passwords app continues to work normally.
Is there a known workaround or fix?
I would appreciate any technical insight or confirmation from other users experiencing the same issue.
Thank you.
