firefox: whitelisting in ${RUNUSER} breaks Wayland and portals

[omega3]

Description

I want to run local profile to be able to use Plasma file picker on Wayland.
I do have xdg-destop-portal and xdg-destop-portal-kde and xdg-destop-portal-gtk installed.

It works well when I have just:

dbus-user.talk org.freedesktop.portal.Desktop
ignore noroot

but when I start adding other entries like:
whitelist ${RUNUSER}/pipewire-0
or
whitelist ${RUNUSER}/kpxc_server

it produces error:

firejail --profile=/home/user/jail/.config/firejail/firefox.local /usr/lib/firefox/firefox
Reading profile /home/user/jail/.config/firejail/firefox.local
Ignoring "dbus-user.talk org.freedesktop.portal.Desktop" and 1 other dbus-user filter rule.

Authorization required, but no authorization protocol specified

Error: we don't have any display, WAYLAND_DISPLAY='wayland-0' DISPLAY=':1'

Parent is shutting down, bye...

So such profile deosn't work:

dbus-user.talk org.freedesktop.portal.Desktop
ignore noroot

whitelist ${RUNUSER}/pipewire-0
dbus-user.talk org.freedesktop.portal.*
whitelist /usr/share/pipewire/client.conf


noblacklist ${HOME}/.cache/mozilla
noblacklist ${HOME}/.mozilla
noblacklist ${RUNUSER}/*firefox*

mkdir ${HOME}/.cache/mozilla/firefox
mkdir ${HOME}/.mozilla
whitelist ${HOME}/.cache/mozilla/firefox
whitelist ${HOME}/.mozilla

# firefox requires a shell to launch on Arch - add the next line to your firefox.local to enable private-bin.
private-bin bash,dbus-launch,dbus-send,env,firefox,sh,which

When I set profile like this:

dbus-user.talk org.freedesktop.portal.Desktop
ignore noroot

#whitelist ${RUNUSER}/pipewire-0
dbus-user.talk org.freedesktop.portal.*
#whitelist /usr/share/pipewire/client.conf


noblacklist ${HOME}/.cache/mozilla
noblacklist ${HOME}/.mozilla
noblacklist ${RUNUSER}/*firefox*

mkdir ${HOME}/.cache/mozilla/firefox
mkdir ${HOME}/.mozilla
whitelist ${HOME}/.cache/mozilla/firefox
whitelist ${HOME}/.mozilla

it shows:

Environment

Operating System: Manjaro Linux
KDE Plasma Version: 5.27.11
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.12
Kernel Version: 6.6.26-1-MANJARO (64-bit)
Graphics Platform: Wayland

firejail version 0.9.72 from official repo
I wanted install from git but I get errors.

Checklist

• The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
• I can reproduce the issue without custom modifications (e.g. globals.local).
• The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
• The profile (and redirect profile if exists) hasn't already been fixed upstream.
• I have performed a short search for similar issues (to avoid opening a duplicate).
  • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
• I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

I added /home/user/.config/portals.conf

[preferred]
default=kde
org.freedesktop.impl.portal.Settings=kde;gtk;

and
/home/user/.local/share/xdg-desktop-portal/
with the same content but it doesn't help.
