Firefox users rejoice!  Today I ran across a post over at DotSauce giving us the heads up on a new Firefox extension called Domain Lookup.

So, what does this baby do?  This domain allows you to select text anywhere in your web browser, then right-click (or CTRL+SHIFT+D) to search for that phrase on your favorite domain registrar, including sites like Moniker and GoDaddy.   This extension also comes with a preference menu so you can edit out top-level domains that you aren’t interested in.

Here are a few screenshots provided by the author:

I don’t register much anymore off the public registry, but I’ve given this extension a try and think it is pretty useful!   I will definitely be keeping it installed in my browser.
