Place FRViewPortExtn.dll relative to manifest file and add the following code to manifest.json

"plugins": [
    { "path": "FRViewPortExtn.dll", "public": true },
  ],

Put this piece of code in your JS(content js\background js\extension js)

var plugin = document.getElementById("pluginId");
var result = plugin.passBrowserResizeData(6,7,8,9);  // call a method in your plugin
