Try to Applications panel - Set how Firefox handles different types of files

I did try that, and I tried changing it to every option they offered for .pdf's and they all operate/act the same when clicked.

Hi Matt, sometimes the application preferences end up with multiple entries, some under "Adobe Acrobat..." and one under "Portable Document Format (PDF)".

If you've fiddled with all of those without success, the settings file that stores these associations might have become corrupted. You can rename or delete it and have Firefox regenerate it. Here's how:

Open your current Firefox settings (AKA Firefox profile) folder using

Help > Troubleshooting Information > "Show Folder" button

Leaving that window open, make any Firefox window active and Exit the program (e.g., File menu > Exit or Firefox menu > Exit)

Pause while Firefox finishes its cleanup, then rename mimeTypes.rdf to something like mimeTypes.old

Restart Firefox. Your PDF preference likely will be reset to the internal PDF viewer, but you can switch it to "Always Ask".

Any improvement?

Try to check the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page and remove the application/pdf part if present or reset the pref to the default via the right-click context menu.

I was making all the changes to the Adobe Acrobat files and didn't see the one lower down called portable document format, once I changed it to ask first it now operates how it should. Thanks for the help everyone.
