Mobile Vikings Balance Extension

Two months ago I changed my mobile provider to Mobile Vikings. Mobile Vikings has a very easy way to check your balance online or on the go. Even though I kinda think it takes too long to load. They have an even better API. Since my browser of choice is Chrome, I decided (yesterday) to make a small extension to check my balance in the background. This is my result until now. (most recent source code can be obtained if you contact me) Everybody who is a Viking and uses Chrome should use it. Updates will be automatically installed. So why not try it? This extension checks your account balance using the Mobile Vikings API 2.0 and Basic Authentication. On first install you will be required to enter you username and password in the options page. It will accept your username or e-mail from your Mobile Vikings account. The options page will close when you save a correct username and password combination and will reappear if an incorrect one is entered. The extension will automatically refresh every hour(can be configured) and a user is able to refresh the extension every minute. If you have any questions, you may ask them in the comments.
