What does that mean? Show the issue. Can you download from this site? see screenshot --> https://www.irs.gov/downloads/irs-pdf What OS? If windows, what security software besides MS Defender are you running? What version of Firefox?

I seem to have solved my own problem. It seems that my "Foxit" program needed to be updated. When I did that, the problem solved itself. Sorry for wasting your time. I appreciate your quick response. Thank you. Arctectk

OUTSTANDING!!! Mark it as resolved so it's off our plate and have a good day.
