Quick answer is that the browserurl used to be easy to get from all browsers, but I think over the years browsers have been less willing to make this info available to outside processes for security reasons. I wonder if we could figure out an alternate solution to this.. perhaps with a browser plugin.. Though you could of course always use a browser-screenshot-plugin for a browser that might save the url.
%scrapetext% if i remember correctly, is only for when you capture a windows object like a button or text control..
