Previously when I need to download a pdf file, there will be a prompt asking what program to open it with, after which it opens automatically after downloading. Now, it the pdf downloads into My Downloads folder and doesn't open automatically. I tried changing the option to 'Always Ask Me Where to Save Files' but this was not my previous setting. I'm not sure if I accidentally changed the settings but I would like it to revert to the window popping up asking if it should open or save whenever I click on 'download' in my gmail.
