More Greasemonkey. This time Technoproxy, "a Greasemonkey script that draws a tiny, unobtrusive speech bubble in the corner of every web-page you visit. Click the bubble, and a transparent windowshade comes down over the current page, showing all the inbound links to that page that Technorati has recently indexed."
If you spend your time reading blogs, & you'd like to see the cosmos for a page without leaving that page, this is the tool for you. I'd be interested to know how the speed of the queries compares with a regular "click the link" cosmos search that has to open in a new window. Is it faster?
