Are you talking about the "River of Search" Script? Does it just allow endless scrolling? I'll copy and paste the description: "The script lets you scroll forever 'till the end (no pages, which makes searching for something way easier), and, well, that's it. But that's pretty fricking awesome and saves a ton of time!" It also requires something to be installed to the browser. I'm not a tech guru so I'm not too confident with determining if something that I'm installing could be malicious or inviting vulnerabilities.
