Other Host Copy utility extensions copy the entire URL. But this works badly when you're trying to do DNS lookups and need the domain for other purposes. For that, Cowboy Copy is what you want!
If you go to https://www.google.com and click on Cowboy Copy, it will copy just "google.com" to your clipboard. It's as simple as that!
