Summary
MetaMask is an extension for accessing Ethereum enabled distributed applications, or "Dapps" in your browser! The extension injects the Ethereum web3 API into every website's javascript context, so that dapps can read from the blockchain. MetaMask also lets the user create and manage their own identities (via private keys, local client wallet and hardware wallets like Trezor™), so when a Dapp wants to perform a transaction and write to the blockchain, the user gets a secure interface to review the transaction, before approving or rejecting it. MetaMask also helps warn you when you navigate to sites that are known to have engaged in phishing, or that have names that are suspiciously similar to popular phishing targets. Because it adds functionality to the normal browser context, MetaMask requires the permission to read and write to any webpage. You can always "view the source" of MetaMask the way you do any Chrome extension, or view the source code on Github: https://github.com/MetaMask/metamask-extension Enables access to: Web 3.0 Dapps NFTs
Safety
Risk impact
MetaMask requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install MetaMask if you trust the publisher.
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Risk likelihood
MetaMask has earned a good reputation and can be trusted.
Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension, especially ones with higher risk impact and/or higher risk likelihood.

Manifest
The manifest file declares the requirements and permissions that a Chrome extension will have access to. By reviewing the manifest, you may be able to determine if a Chrome extension is over-reaching (for example, if an extension is overriding your new tab page, or search provider, or requesting access to your web activities without any good reason).
