PDF file attachments were working fine and now they don't.

I get no error message, but nothing happens when it's set to open in Acrobat. I can view the file in "Preview in Thunderbird" and the file isn't corrupted as I can save to disk and then open in Acrobat.

I tried restarting TB in troubleshoot mode with add-ons disabled, but that did not solve.

Thanks for help!

BTW, .xlxs (excel) files open normally.

It is determined to be a problem/conflict with NordVPN and the "Threat Protection Pro". Disabling this Threat Protection Pro and files now open normally in TB.
