I had Answers installed on my computer and didn't like it. Later, I gave the extension a try. Didn't like it.

Well I thought I'd give the new version of the extension a shot and, Lord have mercy my people, this thing smokes!
Incredibly fast and intuitive. You don't even need to highlight.
I don't know how it does it but, for instance, I clicked on Earth Wind and Fire--just like this, complete, not EWF, and BOOM! chackalackalacka, there's the little popup with info, links, and pictures. You got to check this thing.

Looks great. Answers.com is a great resource, but i hated their desktop tool, too.

The only criticism that I have a this point, is that the popup sometimes displays partially off page, but mostly not.

That wasn't clear. It most often displays correctly
