FireWire Port/Adapter on MacBook? - firewire ethernet adapter

I'm getting a MacBook in a few days and I wonder if there's nothing like a FireWire adapter USB Ethernet / I could get, because my camera does not work on it if it does not. I saw in many forums, but all are more than a year, and I wonder if it's still something that I could now. I do not want to buy either a MacBook Pro.
