Hi,

lately on my Kubuntu 20.10 machine (not updated to 21.04 yet) firefox and firejail do not play nice anymore: FF does not start at all (using FF 88.0).
Interestingly firejail --noprofile firefox and also firejail firefox --safe-mode both work. Because of the working safemode I thought that maybe an add-on causes problems and deactivated all of them - but without success.

Now I am stuck - any ideas?

When starting FF in the console I got as output:

Warning: networking feature is disabled in Firejail configuration file Parent pid 238360, child pid 238361 Warning: cleaning all supplementary groups Warning: cleaning all supplementary groups Warning: cleaning all supplementary groups Warning: cleaning all supplementary groups Post-exec seccomp protector enabled Seccomp list in: !chroot, check list: @default-keep, prelist: unknown, Child process initialized in 111.98 ms

With journalctl:
SECCOMP auid=1000 uid=1000 gid=1000 ses=3 subj=firejail-default pid=238370 comm="GLXVsyncThread" exe="/usr/lib/firefox/firefox" sig=31 arch=c000003e syscall=312 compat=0 ip=0x7fd52482467d code=0x0

Thanks
Frank
