How do I add MetaMask to Google?

How do I go about adding MetaMask, the popular Ethereum wallet and browser extension, to my Google browser? I've heard that it's a great way to manage my crypto assets and interact with decentralized applications, but I'm not sure how to proceed. Could you guide me through the process step-by-step, making sure to highlight any potential pitfalls or considerations I should be aware of? I'd appreciate any help you can provide in getting started with MetaMask on Google.
