When a Dapp wants to perform a transaction and write to the blockchain, you get a secure interface to review that transaction before approving or rejecting it. Because it adds functionality to the normal browser context, MetaMask requires the permission to read and write to any webpage.

Safety
Risk impact
MetaMask requires a lot of risky permissions and is not safe to use. Avoid installing this add-on unless you absolutely trust this 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 fairly good reputation and likely can be trusted.
Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. 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 an Edge add-on, especially ones with higher risk impact and/or higher risk likelihood.
