Hello, Carolyn -
Thank you for your reply and help. I had both an 'AdobePDFViewer.plugin', and an 'AdobePDFViewerNPAPI.plugin' in my Internet Plug-ins folder. It took deleting them both for Safari to then open an online PDF as normal and before.
How bizarre. Apple must have put those Adobe plug-ins in themselves, with Mavericks and Safari 7.0, as I never did myself, and as I wrote, PDFs would open right up in Safari itself prior to my upgrading to Mavericks and 7.0 (I know, as I do a lot of research and reading online, and regulalry come across PDFs, and never had this come up until after the upgrades). How weird.
Anyway... thank you very much though for the advice, it helped and worked, and am back to normal, and all is good again.
Thanks again, and all the best to you,
Carolyn (or anyone else who may have some thoughts on this),
I also have been experiencing difficulty with online pdf's in Safari 7. I used to have things set up so that clicking on a pdf link would result in the file downloading for me to open on the desktop. Since upgrading to Mavericks, Safari now opens another tab that is then filled with lots of text:
" %PDF-1.2 %âãÏÓ 1 0 obj << /Type /Catalog /Pages 2 0 R >> endobj 2 0 obj " etc.
I can either right-click "save to.." or option-click, but...
Anyways, I went searching as you described, but found no Adobe files in user/Library/Internet Plug-Ins. To be throrough, I also checked in the Admin/Library/Internet Plug-Ins.
So, would anyone share either a way to enable Safari to automatically view the pdf's online, or a way to automatically download same for desktop reading?
I'm most likely not going to be of any help, but, reading your situation, the only thing I could think of is in Safari's Preferences > General, at the bottom, you previously had the box checked to "Open "safe" files after downloading', and it perhaps is not checked now?
Otherwise, what Carolyn kindly described for me, did work for me, allowing me to once again view PDFs online within Safari, without the Adobe interference.
