# Contributing
Welcome to firejail, and thank you for your interest in contributing!
## Opening an issue
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:
- [Profile requests](https://github.com/netblue30/firejail/issues/1139)
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 `--noprofile` argument. For example, if `firejail
firefox` does not work, please also run `firejail --noprofile firefox` and
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.
## Security vulnerabilities
See [SECURITY.md](SECURITY.md).
## Opening a pull request
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:
- [etc/templates/profile.template](etc/templates/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 syntax` or just `make`)
- [ ] Update --help
