Right Click - Download Save As

I have a project that I would like to select a series of links on a page (Google search)
After selecting each link in the page, I would like to right-click - save as - and press Enter on the popup window asking to save the file name.
I can get the links on the page setup but need help to finish... thanks

You could download the PDFs just by using an extension or program like Simple Mass Downloader or Multi-File Downloader.

Thanks for the reply, what you are suggesting does not work as these are links to web pages that host the pdf, not pdf direct links. Another consideration this part of an existing workflow.
I assume from what you are saying is that this cannot be done from within webscrper, is this correct?
Thanks for any feedback.
