Print-to-file from Firefox flatpak

I do a lot of print-to-file from the web using Firefox on the Silverblue 32 desktop and am currently testing the flatpak versions of Firefox (Fedora or Flathub). However print-to-file (PDF) from the flatpaks is working intermittently and I was wondering if anyone else had seen this.

I see this issue on Firefox 79 (Fedora remote) and Firefox 80 (Flathub remote). Using Flatseal I have enabled user and host filesystems, and the cups socket. To test, I bring up the print dialog in Firefox, select a file target in my local filesystem - for example my users downloads folder, and print. This sometimes works, and a PDF with the name given is created in the location selected. However most of the time the output file is sent to the tmp file system of the Firefox container, with a junk filename.

You are not alone.
Same here.

Sorry to hear that @felipehw. I think Mozilla maintain the Flatpak on Flathub so we can see how that goes. For me, printing is the main reason I still have to reply the pre-installed RPM version of Firefox in Silverblue.
