Convert a simple Google Chrome Extension to a Firefox Add-on. The chrome extension consists of a tab control that has 2 pages. Each page provides a service on the current URL. The first page contains 2 listboxes, 3 checkboxes, and a button. The second page contains 2 listboxes and a button. When the user clicks any of the buttons, you wrap the options of the corresponding page into the URL of the current web page and send it back to my server to process the request. The server replies back with either an image or pdf. The extension will display the result either directly in the browser or as a download box.
