This is a simple right mouse click menu item that converts dollars/euros to BTC and vice versa. The calculation is made via the blockchain.info API (https://blockchain.info/tobtc)
It can also convert EUR/USD in an input field to BTC and vice versa.
DISCLAIMER: I made this extension as a hobby. So I’m not responsible for any calculation errors! Using this converter is at your own risk… Use it wise and always double check! 😉
