The ChartFox Browser Extension, developed by Cobalt Grid, is a free add-on for the Chrome browser. It enables fully-integrated chart viewing within the ChartFox web app, providing a seamless experience for users.

By integrating with the ChartFox web application, this extension allows for the seamless loading of aeronautical charts from chart suppliers. This integration enhances the viewing experience within the application, offering a more convenient and efficient way to access and view charts.

The extension works in the background by modifying response headers when PDF documents are requested from chart suppliers. This means that users can download the PDF directly from the supplier, while still being able to view and interact with the charts within the ChartFox app.

With the ChartFox Browser Extension, users can enjoy a streamlined and integrated chart viewing experience, making it easier to access and utilize aeronautical charts within the ChartFox web app.
