But most browsers now download or display the PDF automatically when a PDF link is clicked. Firefox opens the PDF in a new window, and I think Safari downloads it. Not sure about Windows.

macOS 12.6.1, LC 9.6.9 rc2

I tried:
on browserNavigateBegin pUrl
   if pURL ends with ".pdf" then
      libURLDownloadToFile pUrl, (specialfolderpath("dektop") & "/test666.pdf")
      pass browserNavigateBegin
   end if   
end browserNavigateBegin

on browserDocumentLoadBegin pUrl
   if pURL ends with ".pdf" then
      libURLDownloadToFile pUrl, (specialfolderpath("dektop") & "/test666.pdf")
      pass browserDocumentLoadBegin
   end if   
end browserDocumentLoadBegin
No file on the desktop, the browser simply ignores the script!?

So any hint on how to download a clicked linke in the browser widget still welcome!
