    Following the update to Firejail 0.9.46, I can’t use Quiterss with Firejail. I’m on Arch and using Quiterss 0.18.4. Quiterss runs fine when not under Firejail – and before the update, it ran successfully under Firejail.

    Here’s the error message I now get:
    ====
    Reading profile /etc/firejail/quiterss.profile
    Reading profile /etc/firejail/disable-common.inc

    Any thoughts, assistance, advice would be most appreciated.

    I have been using firejail just for the sake of –interface=tun0 –defaultgw=10.1.1.2 –dns=8.8.8.8 (badvpn/tuntap) and after the last update (0.9.46-1 I believe) my app stopped working, complaining about access permissions. When I launch it with –noprofile it works as expected – I have my app using separate, socks based network interface. Can I know what has changed regarding this “issue”?

      Could be something in the profile for your application. The best way to debug it is to go in /etc/firejail/app.profile (the specific application profile file there) and comment out the lines one by one. I assume one of the m is creating the problem, probably “protocol” line.

    Hi!

    I want to supply a solution to a strange problem with sound not working in Firefox. I have been searching for days on this problem which I get in Apparmor when using Firejail and Apparmor at the same time (no problem if I only use Firejail or only use Apparmor):

    apparmor=”DENIED” operation=”connect” info=”Failed name lookup – disconnected path” error=-13 profile=”/usr/lib/firefox/firefox{,*[^s][^h]}” name=”run/user/1000/pulse/native” pid=4636 comm=4D65646961506C7E6261636B202333 requested_mask=”wr” denied_mask=”wr” fsuid=1000 ouid=1000

    I have followed the modifications on this site and tried both older and newer versions of Firejail without any luck. The solution was to change the Firefox Apparmor profile from:

    /usr/lib/firefox/firefox{,*[^s][^h]} {

    to:

    /usr/lib/firefox/firefox{,*[^s][^h]} flags=(attach_disconnected) {

    I don’t understand what this is doing but I found it from a similar problem here:

    I hope this can help someone.
