wdf-extension is the client browser extension part of the "Web Digital Footprints and Data Privacy" project from SDIPI.
This project has no prerequisite to build. To run it, you'll need a version of the Chrome browser that can install and execute extensions written in ES 6 (from Chrome 49).
To install the extension on your browser, simply drag and drop the src folder into the Extensions page of Google Chrome.
If you're looking to package the extension for the Chrome Store, either compress the content of the src directory in .zip format yourself, or if you have npm installed, run the following in the project's root directory :
npm install
npm run build
