Using gmail from a HP Laptop running Win 10 with Firefox Quantum 62.0.6(64), I now find an IRS pdf form that I must enter quantities of product on, will not download properly in order to enter any new info. Luckily, I have access to a condo Juno.com account and wife’s Comcast acct which have no problem with tyhe Adobe., But other people may not be as lucky. Tried to get to Adobe AND GMAIL help with no success.
Are you saving the file, then opening it? Or are you opening the file directly from the download source?
When the file opens, does it open in the actual Adobe Reader program, or is it opening in a browser?
