Ted Rheingold has created a neat free people search extension for users of the Firefox web browser called “Who Is This Person?”

This handy web search extension allows users to highlight any person’s name on a web page to find out more about the person through information published on the web’s top social networking and people search sites like – MySpace.com, LinkedIn.com, Wink.com, Facebook.com, Wikipedia.com, Technorati.com, Google News, Yahoo People Search, Spock.com, WikiYou.com, ZoomInfo.com and others.

This is an easy way to quickly find information from numerous search sites, using one tool.

You can read more about the “Who Is This Person?” people finder extension and download it at Mozilla.org.
