Hi: Instead of deleting the plugin "AdobePDFViewerNPAPI.plugin" you can use it's functionality. If you place your cursor over your document you can see a print and save icons and you can use them. You can also see and "Acrobat" symbol which when clicked opens the plugin menu in the Safari page. If you have deleted the plugin you can reinstall Adobe Reader and the plugin will be reinstalled too.

Please, let us know if it worked for you.

I had the same problem. Apparently (as I understood from another post about the same problem) it appeared after updating the Acrobat software (Adobe Acrobat 8 Professional 8.3.1).

The solution did work for me (Safari 5.1.5 on Mac OS 10.6.8).

Now I'm back to the old situation where the pdf file shows up smaller on the screen (no more as wide as the screen, but as high as the screen) and to go back a page I again need to use the Back button of Safari, instead of sweeping on the trackpad.

However the main reason to reply on this post is the question whether someone (of Apple ?) does notify Adobe about this problem or do they observe these kind of posts?

As I mentioned before, I did not delete the "AdobePDFViewerNPAPI.plugin" plugin. I just don't use the Safari "print" and "save" commands. I move the cursor above the document, near the bottom, and Adobe "print" and "save" commands appear. I use them without any problem.If you have deleted the plugin you can reinstall Adobe Reader and the plugin will be reinstalled too.

This is how it looks. (Bottom of the document.)

Thanks rgonzaleza for your replies. I already noticed it, after replacing the plugin. (Such files never go into the trash bin, but to some other directory, just in case ...)

What I dont' like is that companies like Adobe do not comply to standards. When saving files I just want to use Cmd-S and not being bothered with another "new and easy" way of doing things.

The better standardization is why I like Apple and hate Microsoft.
