So I would like to either create a Tampermonkey script or a Google Chrome extension to open a new window that contains data from a site (that I do not own). The site's data is displayed in a format that is hard to read (need to uncollapse multiple rows to reach relevant data).

The new window should open when clicking on the first uncollapsable row and display all the data from that row in the window. I do not know if this is possible to do, as I'm not sure if this new window could even be created w/o an actual hosted URL.
