FF won't download pdf files
I have FF 104.0.1 (64-bit). Windows 7 Pro x64. Acrobat 9 Pro. When I select a pdf in a web search FF ask if I want to save or open in Acrobat. If I select open in Acrobat nothing happens. If I select download it download a 0 byte file that Acrobat says it can't open. I have FF set to "ask" for pdf files. If I set options to open in ff, it does open. Everything worked fine up until about a week ago. I have had a couple of FF updates since then. The pdf files save or open in Acrobat properly if I use Chrome. I have rebooted the pc. Wish I could rollback updates to see if that is causing the issue.
