This extension identifies hidden, unlinked parameters. It's particularly useful for finding web cache poisoning vulnerabilities.
It combines advanced diffing logic from Backslash Powered Scanner with a binary search technique to guess up to 65,000 param names per request. Param names come from a carefully curated built in wordlist, and it also harvests additional words from all in-scope traffic.
To use it, right click on a request in Burp and click "Guess (cookies|headers|params)". If you're using Burp Suite Pro, identified parameters will be reported as scanner issues. If not, you can find them listed under Extender->Extensions->Param Miner->Output
You can also launch guessing attacks on multiple selected requests at the same time - this will use a thread pool so you can safely use it on thousands of requests if you want. Alternatively, you can enable auto-mining of all in scope traffic. Please note that this tool is designed to be highly scalable but may require tuning to avoid performance issues.

Web Cache Entanglement update
Here's a video of the new features being used to find a fat GET cache poisoning vulnerability in a demo site using Rack::Cache Another video targeting a real site is coming soon - I'm just waiting on the target to patch.
