Wow, surprisingly convenient wallet for my Ethereum, MetaMask sits in my Firefox with the ability to create different wallets, see my transactions on Etherscan, buy, send, and receive on all wallets, back up my private keys, and lock up MetaMask when I'm done using it. Plus I can install MetaMask on all my desktop, laptop, phone Firefox installs and have access to all my wallets via my seed words. Very nice.
