MetaMask is a cryptocurrency wallet which can be used on Chrome, Firefox and Brave browsers. It's also a browser extension. This means that it works like a bridge between normal browsers and the Ethereum blockchain. The MetaMask extension can be used for storing keys for Ether and ERC-20 tokens on three different web browsers. It also allows users to browse the Ethereum blockchain from a standard browser.
