Original GitHub issue: https://github.com/netblue30/firejail/issues/3205

When I download a PDF for example and try to open it from the download list in Firefox (Ctrl+Shit+Y), it says that the link has to be opened by an app and that's it. It won't open Okular for example.

I already added

private-bin okular

to firefox.profile, so at least I already see a PDF icon in the download list.

System

FF 72.0.2
firejail 0.9.62
Archlinux

If you have configured Firefox to use a specific application to read PDF files instead of using the built-in PDF viewer this is expected behavior. Adding 'private-bin okular' to firefox.profile is not enough to get the functionality you're after IMHO. In fact, I'm quite surprised that Firefox is even starting at all by doing so. The private-bin option isn't used in any of our default firefox-related profiles. Hence adding it would limit the set of acessable binaries to just 'okular'.

We have this in /etc/firejail/firefox-common.profile:

# Uncomment the following line (or put it in your firefox-common.local) to allow access to common programs/addons/plugins.
#include firefox-common-addons.inc

Do you have a ~/.config/firejail/firefox-common.local file referencing 'include firefox-common-addons.inc'?

This is the full line I had in firefox.profile

private-bin bash,dbus-launch,dbus-send,env,firefox,sh,which,plasma-browser-integration-host,okular

Do you have a ~/.config/firejail/firefox-common.local file referencing 'include firefox-common-addons.inc'?

Nope, not yet, but I am going to test it with the firefox-common-addons.inc :)

That makes more sense 👍.

I think you can solve this by including firefox-common-addons.inc. Feel free to close at your discretion. Good luck.

I tried it but with no luck. What I can do though is to click on the button to manually pick the app to open a PDF, where I can navigate to /usr/local/bin/okular, but that's not the way it should work.

IIRC I could solve it adding okular to private-bin, but FireFox kept asking me which program I wanted to use to open a PDF, though luckily okular was already in the list -- just its icon was missing.

Nonetheless, for the moment I disabled FireJail as it's way too time consuming for me to configure it correctly and to adjust all kind of profiles in the moment.
