Eric thank you for taking the time to reply. All the sites seem to working again in Firefox v.27 and IE v11 and I have no idea why??
I know that Firefox has the option not to use Acrobat Reader but I still left it as my default pdf reader for Firefox.
The only noticeable difference since this all started is that Firefox still has a small delay before it opens and no blue bar. This small delay is about the same amount of time it took for the blue bar to finish as the pdf opened. IE still has the same blue bar and opens immediately.
Thanks again for your input….Greg
