This extension adds a toolbar button to your browser. You can click it to view your cryptocurrency wallets' balances and their values in fiat. It supports BTC, LTC, ETH, DOGE and DASH and can convert the balance in USD, CAD, EUR and CNY.

Click on the "+" icon to add a wallet. Choose the type of crypto, the type of fiat and input all the addresses you want to monitor in the same wallet. Each address should be separated by a newline and nothing else. Then, click the add button and close the popup. When you reopen it, you can look at the balance in your wallets. You can remove wallets clicking on the "-" icon.

The values are updated every 10 minutes or when you add a new wallet.
