What is MetaMask?
MetaMask is an innovative Firefox add-on serving as a fully functioning Ethereum wallet in your browser. This extension plays a crucial role in accessing Ethereum enabled distributed applications, or 'Dapps'. It injects the Ethereum web3 API into every website's javascript context to allow dApps to retrieve information from blockchain. It also allows users to create and manage their own Ethereum identities, facilitate transactions and interact securely with dApps.

Summary
Analyze keywords

An Ethereum Wallet in your Browser MetaMask is an extension for accessing Ethereum enabled distributed applications, or "Dapps" in your browser!

Watch an introductory video here.

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.

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-plugin

Enables access to: Web 3.0 Dapps

Absolute memory hog which makes Firefox run slower and thus your entire PC as well. I suggest using Enkrypt, which is much more user friendly as well due to not making you import tokens the way MetaMask does.
