Hey guys I need help.
There was a video or gif posted here in which there was tool running with in Chrome or some browser where the guy first open a web page with adblock disable and then with enable. The tool show the links in pages present in tree like graph. And with adblock enable the graphs was smaller. I want to know the name of particular tool

Sorry, I don't know how to describe it, but it's driving me crazy now. I already searched all Chrome inbuilt urls.
