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 documentsF-Turtle documents
  3. A Web Service Console -- that simplifies RESTful interaction by exposing HTTP call parameters. A powerful mechanism for toggling Identity when working over TLS connections -- such that identity changes don't require browser restarts
  4. 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
  5. CSV and JSON documents support with regards to data visualization.
  6. One-click saving of Structured Data to SPARQL-accessible Knowledge Graphs, subject to ACLs
  7. SuperLinks that connect words and phrases in current documents to entity descriptions across Knowledge Graphs, via a single-click
