Released yesterday, Hyperwords is a nifty extension for Firefox that makes every word on a Web page a potential hyperlink to an array of search, reference, blogging and other tools. Simply highlight a word or group of words, and a pop-up menu appears offering options to search, reference, map, shop, copy, e-mail, tag, blog or translate. Each option in turn leads to a submenu of further options, so “search” leads to submenus where you can select the type of search and where to search — search Web sites using Google or for pictures using Flickr, for example. The Hyperlinks Blog has yesterday’s announcement of the launch. Install the Firefox extension here. A version for Internet Explorer is coming, the site says.
