The functionality of this extension is twofold:
First, it checks whether a visited page contains GoodRelations in RDFa, Microdata, or both. If GoodRelations code was found, the extension's button in the menu bar becomes clickable (it changes from gray-shaded to colored). The behavior of this button is customizable, i.e. one can provide a target URI for Rest APIs that can do something meaningful with the metadata found, e.g. Google's Rich Snippets Testing Tool, the RDF Translator, or Linter.
Second, the user is free to decide whether to enable an option that helps developers to track pages that contain GoodRelations metadata. In the configuration section, one may check a box that will prompt the extension to ping the GR-Notify service on each visited page where GoodRelations is found. For those who worry about privacy, it remains to say that this functionality is disabled by default and will be anonymous as long as no e-mail address is provided!
