Welcome to firejail, and thank you for your interest in contributing!
We welcome issues, whether to ask a question, provide information, request a new profile or feature, or to report a suspected bug or problem.
If you want to request a program profile that we don't already have, please add a comment in our dedicated issue:
When submitting a bug report, please provide the following information so that we can handle the report more easily:
- firejail version. If you're not sure, open a terminal and type
firejail --version. - Linux distribution (so that we can try to reproduce it, if necessary).
- If you know that the problem did not exist in an earlier version of firejail, please mention it.
- If you are reporting that a program does not work with firejail, please also
run firejail with the
--noprofileargument. For example, iffirejail firefoxdoes not work, please also runfirejail --noprofile firefoxand let us know if it runs correctly or not. - You may also try disabling various options provided in
/etc/firejail/<ProgramName.profile>until you find out which one causes problems. It will significantly help in finding a solution for your issue.
Please note: If you are running Debian, Ubuntu, Linux Mint, or another related distribution and you installed firejail from your distro's repositories, please ensure that all of the following packages were installed:
- firejail
- firejail-profiles
A common source of issues is that firejail-profiles was not installed when installing firejail.
See SECURITY.md.
Pull requests with enhancements, bugfixes or new profiles are very welcome.
If you want to write a new profile, the easiest way to do this is to use the profile template:
If you have already written a profile, please make sure it follows the rules described in the template.
If you add a new command, here's the checklist:
- Update manpages: firejail(1) and firejail-profile(5)
- Update shell completions
- Update syntax files (run
make syntaxor justmake) - Update --help
You are highly encouraged to add your own tips and tricks to the wiki.
