Does anyone know of an addon that can prefetch data on PDF's on a Google search

Does anyone know of a prefetch addon that can scan a Google search for PDF’s and place the file size data and perhaps the page count data on the front search page so that you can see what sort of quality the PDF actually is before you click on the link to look at the PDF. I do a lot of searches on PDF’s and find its quite random if you get good or bad results. A pre-fetch addon would be good, if there is not one maybe someone could make one.
