icloud-passwords-firefox

This Firefox extension lets you securely fill passwords from iCloud Keychain® when signing in to websites.
It also provides you with strong passwords, one-time codes, and passkeys to secure your online accounts.
Your passwords are automatically synchronized accross your Apple and other compatible devices.

Installation

➡️ Recommended: Download this extension from AMO (addons.mozilla.org).

Alternatively, download the latest GitHub release and install it on Firefox by navigating to about:addons.

Refer to the following table to see if your configuration is supported:

Platform	Version	Status
	>= Sonoma (14)	✅ Fully supported
	<= Ventura (13)	❌ Unsupported
	>= 7	⚠️ Requires additional setup (see below)
	<= Vista	❌ Unsupported
	Any	❌ Unsupported

Additional setup

For some operating systems, additional steps are required for the extension to work:

1. Install iCloud for Windows.
2. Enable the Passwords option.
3. Click on Install Extension... for either Microsoft Edge or Google Chrome.
4. Download the icloud_passwords_install file from the latest GitHub Release.
5. Run the downloaded executable as administrator.
6. Restart Firefox, and you should be good to go!

Why is this required?

macOS Sonoma (14) and later come with PasswordManagerBrowserExtensionHelper.app preinstalled.
It's a utility which allows Apple's iCloud Passwords Chrome and Edge extensions to work.
This extension uses the same utility, so it works natively without any further steps.

Unfortunately, this utility is not available on previous versions of macOS, on Windows, nor on Linux.
For such operating systems, this utility needs to be replaced. iCloud for Windows serves this purpose.
By default, iCloud for Windows does not grant access to Firefox to access passwords.
The provided executable thus enables the communication between Firefox and iCloud for Windows.

The source code for the Golang executable is available in the scripts/install directory.
