Save PDFs from Chrome Again
If you suddenly lose the ability to save a PDF from your web browser, the problem may be related to add-ins you have installed.

Go to the list of extensions in Chrome, by entering 'chrome://extensions' in the address bar.
If you have multiple add-ins for viewing or editing PDF files, turn one of them off, and re-launch the browser. This may give you back the ability to save PDF files from Chrome again.
