This extension displays the current btc price on the badge icon.Displays the current Bitcoin price in your selected currency, pulled from your choice of a few exchanges. The price updates every 5 minutes.

-btc-e
-coinbase
-coinbase exchange
-kraken

Update 1.4.0: Added two new exchanges (coinbase exchange and kraken) and also added the ability to switch currencies (USD and EUR). Also removed mtgox.

Update 1.3.0: Added an options page to choose which exchange to pull ticker data from. (Note: Due to this change there are new permissions, so you will need to re-enable the extension and accept these.)

Update 1.2.1: Updated to mtgox api 2, removed no cache, as it looks like it was being blocked on mtgox's end.

Update 1.2: Added no cache directive so the value should always be the latest. Some users were experiencing the data not updating as often as it should because their browser was caching it.

Update 1.1.1: Changed to use https for mtgox api.

Update 1.1: You can now click the icon to manually update the current price. Be warned, doing this too often (like many times in a few seconds) could get your ip blocked.
