Regarding your desktop, MetaMask primarily functions as a browser extension. However, you can use it on your desktop by installing a compatible browser like Chrome or Firefox. If you prefer a standalone desktop application, [b]Metamask Chrome Extension[/b] provides a desktop version as well. Visit the official MetaMask website, download the desktop version suitable for your operating system (Windows, macOS, or Linux), and follow the installation instructions. This allows you to manage your Ethereum assets and interact with DApps directly from your desktop, providing flexibility in how you use MetaMask across different platforms.
