Identify is a Firefox extension that can be used to retrieve information about individuals on social networking sites. It works by visiting a profile page on a site and pressing the [alt i] keyboard shortcut to open the Identify overlay. Mac users press [ctrl i] for the same effect. The Firefox add-on will then display a stylish overlay containing various information about the selected individual including – if available – a link to the homepage, a short about me paragraph and links to other social networking and media sites that the individual has accounts at.
Below is a screenshot of how the information are displayed in the web browser. Example of Identify showing Sarah Perez’s information.

The developer does not provide extensive information about how the Identify add-on calculates the data except for the following short sentences found on the project page:
It makes extensive use of Google?s Social Graph API to find out about which sites an individual has profiles on and then uses YQL API to collect the information.
It can obviously only be executed on supported sites. The usual suspects like Twitter, Digg, Flickr or Friendfeed seem all to be supported by the add-on while sites like Ghacks are not. A link is provided for each identified profile on another service making it very easy to follow the trail of the individual.
