Chrome Extension: base64 decode query string data

chrome-extension.js

/**
 * This is the beginnings of a Chrome Extension that will extend the Chrome Developer Tools Network panel using
 *  the webRequest and devTools APIs.
 * This will be very useful for debugging the calls that the Mixpanel snippet makes out when you make
 *  Mixpanel API calls in your code
 */

function d64json(data){console.info(JSON.stringify(JSON.parse(atob(data)),null,2));}

/*
 * Then call the d64json function with your pasted in data from a Mixpanel call from the query string parameter named `data`

Placed on hold for now as I have enabled debug mode for non-production with Mixpanel:

mixpanel.init('ID', {debug:true});
