These steps may help as well:

Delete the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.

Set the pdfjs.disabled pref to true on the about:config page to disable the build-in PDF viewer.

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.

When you removed the PDF plugin, did you confirm that Firefox is no longer aware of it? It should no longer appear here:

orange Firefox button (or Tools menu) > Add-ons > Plugins category

Firefox periodically scans the registry to update that list, so depending on how you removed it, Firefox might believe you have it installed but a file is missing... as a workaround for that, you could try using the Disable button.

RESOLUTION (seems not logical, but this worked):

Firefox would do nothing other than ask me to install the Firefox plugin for Adobe, which I accepted. This process leads to re-installing Adobe Reader. After installing Adobe Reader, all of the defaults that I previously had set to use Adobe Standard were re-set during the Adobe Reader installation to use Adobe Reader interally in Firefox.

After re-installing, I was able to load the document that previously I was unable to load (using Adobe Reader inside Firefox). I changed all of the Adobe defaults (under TOOLS/OPTIONS) to "always use Adobe Standard" instead of "Use Adobe Reader (default)". I was then able to open the document using Adobe Standard.

It appears that the following process solved the problem: > uninstall Adobe Reader > reinstall Adobe Reader (and the Firefox Adobe plugin) > change the defaults from "Use Adobe Reader (default)" to "Adobe Standard [release number]"

Note: I have Firefox 21.0 installed, and Adobe Reader XI 11.0.3 installed prior to, and after, this issue.
