Apple now has a dedicated iCloud Passwords add-on designed for the Firefox browser, which means Firefox users can access passwords and logins stored in the Passwords app or iCloud Keychain when using Firefox on a Mac.
The extension is being distributed by Apple, but it appears that it was originally created by a third-party developer and later taken over and updated by Apple.
