This extension integrates Crawljax, Selenium and JUnit together.
The intent of this extension is to aid web application security testing,
increase web application crawling capability and speed-up complex test-cases execution.
Install the BurpCSJ extension into Burp.
Choose the URL item from any Burp tab (e.g. target, proxy history, repeater).
Right click on the URL item.
Choose menu item "Send URL to Crawljax".
Crawljax will automatically start crawling the URL that you choose.

If you are planning to use Chrome, IE or PhantomJS browsers you would need the following drivers/executables:
