PwnFox is a Firefox/Burp extension that provides useful tools for your security audit.

popup

Connect to Burp with a simple click, this will probably remove the need for other addons like foxyProxy. However if you need the extra features provided by foxyProxy you can leave this unchecked.

Supports both HTTP and SOCKS5 proxy protocols. Configure the protocol in the extension settings.

PwnFox give you fast access to the Firefox containers. This allow you to have multiple identities in the same browser. When PwnFox and the Add container header option are enabled, PwnFox will automatically add a X-PwnFox-Color header to highlight the query in Burp.

PwnFoxBurp will automatically highlight and strip the header, but you can also specify your own behavior with addons like logger++.

tabs burp

PwnFox add a new message tab in you devtool. This allow you to quickly visualize all postMessage between frames.

You can also provide your own function to parse/filter the messages. You get access to 3 arguments:

• data -> the message data
• origin -> the window object representing the origin
• destination -> the window object representing the destination

You can return a string or a JSON serializable object.

Inject you own javascript code on page load. The code will be loaded as soon as possible. This can used to add dangerous behavior detection, or just to add extra function to your js console.

Be careful, the injected toolbox will run in the window context. Do not inject secrets in untrusted domains.
