Cooliris Previews is a Firefox extension that enables you to hover your mouse over a search engine result in Google, eBay and Craigslist, and preview the page (or image) in a popup dialog without having to leave the result page. The borderless popup will automatically close when your mouse moves away, so there is no need to manually close it. Cooliris Previews includes another handy feature that lets you select a word on any web page and right-click on it to preview the search results for that keyword in Google, Wikipedia or FreeDictionary. Future versions of the software will include support for additional sites, including MySpace and others.
