MetaMask is a neat browser extension (for Google Chrome, Firefox, Opera, and the Brave browser) that is also an Ethereum wallet.
The code for MetaMask seems to be available here at GitHub.
Considering the security mechanisms available in Ethereum, what are the risks with using it as a wallet?

If code is in github means product is safe & secure?. Well I wan to clarify 2 points:
As per @danfinlay Today, MetaMask is indeed a "hot" wallet, in that you use it on a computer connected to the internet. This is usually considered less secure, because if a machine is on the internet, it could be accessed remotely, and keys could be stolen.
