Original GitHub issue: https://github.com/netblue30/firejail/issues/3252

MasterpdfEditor is jailed with masterpdfeditor5.profile
Thunderbird is not jailed.

When opening a pdf directly from Thunderbird, Masterpdfeditor says cannot read it from /tmp/mozilla...etc.

If i open the pdf directly from /tmp, it will open.

What do i need to do to allow it to open it from Thunderbird?

Please dont tell me that thats its intended purpose and that i should first save the file. There's already no network to masterpdfEditor, so saving the file and then opening it is just tedious. How do i get around this to allow to open via /tmp ?

firejail - version 0.9.58.2

Create it:

mkdir -p ~/.config/firejail
echo "ignore private-tmp" >> "~/.config/firejail/masterpdfeditor5.local"

@svc88 the .local ones are optional for users to create.
