I have the current Adobe Reader installed but am running into an issue opening online PDF docs. My computer says "This PDF document might not be displayed correctly. Open with a Different Viewer."
I tried today and got this message:
To view the full contents of this document, you need a later version of the PDF viewer. You can upgrade
to the latest version of Adobe Reader from www.adobe.com/products/acrobat/readstep2.html
For further support, go to www.adobe.com/support/products/acrreader.html
On Mozilla Firefox Browser 21.0
How can I correct this please?

Strange as it may seem, FireFox just ignores Adobe Reader, and so you get this error. Just save the file to your desktop and open it there. Or start Internet Explorer for a one off.

In Firefox, type "about:config" (minus the quotes) in the address bar.
A window will open with a warning.
Click "It's OK, I'll be careful" and open the configuration window.
Type "js" (again, minus the quotes) in the search bar at the top.
In the results you'll see "pdfjsviewer disabled" with a value of "true".
Right click "true" and toggle it to "false".
Close the configuration window.
In Firefox options (Tools>Options for Windows - Firefox>Preferences for Mac), under the Applications tab:
Locate Portable Document Format (PDF) or Adobe Acrobat Document(PDF)
Click the drop down on the right and select Adobe Reader as the app to preview in Firefox.
This will disable Firefox's built in PDF viewer and enable Adobe reader's plugin for viewing PDFs.
