I ordinarily open way too many tabs. I see a link that I might be interested in, I control/command-click it to open in the background and continue on the current page. Before long, I may have dozens of tabs that need follow-up. CoolPreviews will eliminate many of those by providing the smoothest implementation I’ve seen of popping up an embedded, scrollable window of any given link. A quick mouse over, scan and I can move on or continue with my ingrained research path.

That’s not all the extension accomplishes. You can create stacks of sites to step through as well as do preview searches of highlighted text at any number of differ sites.

So, for those of you that haven’t seen it, consider taking a look.
