Is there any web application to render multiple URLs in a single page/window as a grid? I want to check some updates injected by ajax. These updates reflect on multiple pages (10+ pages) at the same time. So keeping track of all pages at the exact moment is not practical with tabs/multiple windows. Is there any Web Applications, Extensions, Add-ons, or even desktop software for this purpose?
I want it to look like you are watching at multiple monitors with each monitor on different page. See image given below:
