Can't open, download or view PDFs - Tried all fixes recommended on this site!
I updated Firefox yesterday and now I am suddenly unable to open, download or view PDF documents on my mac. I just get a blank page in Firefox when I click on a PDF link.
I tried every fix I could find on this forum and others:
Disabling both the Acrobat NPAPI Plugin and the Acrobat Reader Plugin
delete the mimeTypes.rdf file in the Firefox Profile Folder to reset all file actions.
installing another PDF reader plug-in
Cleared download history
Checked status of Download Folder - no 'user set' values
Fixed all Mac Permissions
Still same thing PDF tries to open in a new tab - I just get a blank window… even when my PDF Preferences are set for the pop-up dialogue to show so I can choose whether to save, open or view.
AND my Firefox preferences are set for viewing in Acrobat Pro X (this was how I had it set up before the update and had no problems - all PDFs opened in this application. (my preferred)
I am stumped. Anyone have any fresh ideas? HELP!! :) Thank you

The Adobe Reader plugin may not be working properly on Mac.
Disable the Adobe Reader plugin in Firefox (Tools > Add-ons > Plugins) and use the external Adobe Reader application or Preview application instead.
PDF files may be found under entries like Portable document or Adobe PDF document.
- Firefox > Preferences > Applications > Adobe PDF document : Use Adobe Reader
Sorry for the giant paragraph - there were actually paragraph returns when I typed my question. At any rate, had already tried that, with no success.
HOWEVER I did eventually solve the problem by REMOVING NITRO PDF READER (which had been functioning fine prior to Firefox update) extension. Instant fix.
Hope this helps someone else. That was a lot of time and energy to figure out the culprit.
