if it does not fit you on other coins, you can use MyEtherWallet as a simple web wallet and always go into it through the browser. But if you do not like the prospect of constantly copying and pasting your private key into the browser, you can make working with your current address much safer: if you operate with small amounts and from time to time use Ethereum for purchases, I recommend installing the MyEtherWallet extension for Chrome or MetaMask
