Just got this one today! It is a firefox addon that helps you find available domains at your favorite registrar while you are viewing sites. Simple to download and use (I tried it quite a few times and it works as advertised, if not better). I blogged about it at: http://www.dawghost.com Plus put up a list of expired domains. But you better hurry and check out the list and grab what you want before someone else does! Saw a couple of 5 letter .com domains.
