I can't save a .pdf from Science Direct
There is a workaround for this problem which we recommend using until the cause of the problem is found.
(The problematic "save" icon is shown here)
To workaround the problem, right-click the PDF logo in the results list or item record and choose “Save link as…” (Chrome, Firefox) or “Save Target As…” (Internet Explorer).
You should now be able to choose a place to save the .pdf file.
