Original GitHub issue: https://github.com/netblue30/firejail/issues/760

Somehow firejail thinks that firefox.profile contains an invalid line and exits.
This happens for example for firefox (and also for icedove; those are the only profiles where I noticed that).
(Note that it complains about a line number which doesn't exist.)

$ rm -rf .mozilla .config
$ wc -l /etc/firejail/firefox.profile
50 /etc/firejail/firefox.profile
$ firejail --debug firefox
Autoselecting /bin/bash as shell
Command name #firefox#

@reinerh I can't reproduce it either on LMDE 2. What distro are you using?

Fixed: 24f53cde1d

There are some obscure differences between exit() and _exit(), described here: http://www.unixguide.net/unix/programming/1.1.3.shtml. I ended up fixing this problem all over the place. Thanks for the bug.
