Question:

I want to access my browser's network console output via JavaScript or maybe another language.

<em>Here is a screenshot of the Firefox network console on Youtube:</em>

I just want to retrieve every URL my browser GETs, and do it in JavaScript, if possible (I insert my scripts in the page using the Firefox Scratchpad).

Thank you.

<h2>Edit: A bit more information about my project</h2>

I want to download a collection of "text to speech" samples generated by a website. But I don't want to use their API, because I know exactly how much samples I need (the number is above 300, so I don't want to do it manually).

By using a normal JS script inside your browser won't give you access to this Firefox Panel, due to security reasons. But an alternative (For Google Chrome) is to type chrome://net-internals/#events in the Chrome address bar. This will open the Network Monitor. There you can type Ctrl+Shift+J or Cmd+Option+J (On Mac OS) and gain access to all HTTP events with JavaScript directly in the console.
