Printing to a PDF worked perfectly until I upgraded from FF version 56 to 58.0.2. FF tells me this is the latest version. The PDF gives either/or a blank page or an error message that simply says, "An error occurred while printing" and a blank page is the result. I just hate updating FF. It always produces problems.
PC, Windows 10.
Sorry for the delayed response and inconvenience caused. As per the description above, you are not able to Print to PDF with Firefox 58.0.2 browser, is that correct?
Please make sure you are opening the file using the Adobe plugin, not the built-in PDF plugins of the browser firefox http://helpx.adobe.com/acrobat/kb/pdf-browser-plugin-configuration.html

Try updating the Acrobat once from help>check for updates, reboot the machine after installing the updates. Also, update the Firefox, and see if this brings any difference.
