Several programs are no longer playing nice with each other.
Several of the insane rapid release FireFox versions have had problems with PDF files.
Now, I just download the PDF and then open it in the standalone PDF viewer. [I use PDFExchange, rather than Adobe.]
I have had similar problems with IE and FF.
Adobe Flash would not work with the FF rapid release version 13.

I cringe every time I see software ‘upgrade’ or ‘update’ recommendations. Upgrades/updates seem to create more problems that they fix.
I AGREE, mostly I let them alone until I just can't stand their reminders any longer.
I have picked up several FIXES, ways around the problem on this thread.
One was to pull the PDF file to desktop: WORKED
Another: to change the internet preferances in ADOBE, to uncheck the PDF.
That last one worked with a cavaet:IE now gives me a warning box of: TO help protect your Security, Internet Explorer blocked this site from downloading files to your computer, click for options.....X
I can live with both these options. Leave it to VERY SMART FREEPERS, THANKS.
