Icloud Passwords Firefox

Abstract

1. Introduction

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.

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.

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.

2. Objective

Firefox extension which lets you use your passwords stored on iCloud Keychain®.

This project demonstrates how TypeScript can be applied to a real-world Cybersecurity & Ethical Hacking problem.
