About this extension
This powerful browser extension adds the following functionality to your Firefox browser:
  1. Discovery of Structured Metadata (POSH, JSON-LD, Microdata, RDF-Turtle, and RDFa) embedded in HTML Documents
  2. Handling of content-types beyond HTML -- enables your browser to natively render JSON-LD and RDF-Turtle documents
  3. A Web Service Console -- that simplifies RESTful interaction by exposing HTTP call parameters
  4. A powerful mechanism for toggling Identity when working over TLS connections -- such that identity changes don't require browser restarts
  5. A "Copy & Paste" feature for exporting content from RDF-Turtle, RDFa, JSON-LD, or POSH tabs to RDF-Turtle or JSON-LD formatted clipboards, for reuse and remixing elsewhere.
