Interclue

I've just come across an interesting add-on for Firefox by a Christchurch based company. Kiwi ingenuity has done it again. I'm keen to try it out, as it has been garnering good reviews, and this one does a fairly good summation for me:

Interclue is a Firefox extension that adds more information about a link when you hover over it. It's not that annoying as the famous Snap tooltip and it certainly provides much more information about the page....the most impressive thing is that all this data loads almost instantly and it's actually useful, especially when you want to judge the quality of a search result (including if it returns a server error) ....a brilliant tool. - Google Operating System Blog

If you use Firefox, you might want to give it a try.
