Amazon. Instead of multiple pages with only 12 items per page, i'm looking for an add-on that gives me the ability to search through the products on one long page. The same goes for eBay and Google shopping. Does an add-on like this exist?

I'm looking for an add-on that turns multiple pages into one long page. Like when i'm shopping on Amazon. Instead of multiple pages with only 12 items per page, i'm looking for an add-on that gives me the ability to search through the products on one long page. The same goes for eBay and Google shopping. Does an add-on like this exist? Thanks in advance.
