The MetaMask extension provides an API to websites you visit so they can interact with the blockchain. As of December 2020, they stopped injecting the web3.js API by default, which improves security and performance, but can break older and unmaintained websites. With this extension in combination with MetaMask, you can continue using those older sites as before.
