I frequently try to save pages as PDFs. When I print the page directly to a printer, no problem. When I save the PDF, it's usually munged and not a valid PDF file (very small or 0 bytes). Example URL: https://www.nytimes.com/2019/07/01/science/bacteria-microbes-electricity.html

Makes an empty PDF while when I do Print and then Save as PDF. I'm on Apple OS 10.13, using Firefox 67.0.4. This problem has been with us for a while (> 1 year I believe) and happens on all my machines.

I need to update Mozilla Firefox ( (I currently have version 67.0 (32 Bit) installed. Mozilla Firefox for Ubuntu canonical 1.0). It was initially uploaded (a few years ago), via Package Manager. Because for a while, I no longer receive support, that way I neither receive updates. So, I can't update again Mozilla Firefox via Package Manager. Please let me know how can I proceed to achieve this update. Thank you!

I am constantly getting notifications from Firefox and cannot cancel them. They appear on my login screen and on home screen (see screenshot). Cannot swipe them away and cant find way in FF. Only way to get them to go away is to restart phone.

Usually notification comes from an active web page but now getting them from Firefox itself. Current one just says "About home".
