Easily check your balance and send Bitcoins from Chrome.
This extension allows you to view your Bitcoin balance and easily make payments by selecting and right-clicking a Bitcoin address or by doing the same with specially formatted images.
The extension will also look for Bitcoin addresses on the pages you visit and convert them to links which bring up the send dialog when clicked. This new feature can get confused, but it should work in most cases.
You need will need Bitcoin installed and running in -server mode to accept JSON-RPC connections. To do this you must set the values of rpcuser and rpcpassword in your bitcoin.conf file (in the data directory, with your wallet.dat - you may need to create it). Once loaded, you will need to right the Bitcoin icon and choose Options to configure the extension to match your bitcoin.conf settings.
Once you get it working, your balance should show when you click the Bitcoin browser icon.
