I’ve just installed Firejail, now what?!

Integrate your sandbox into your desktop by running:

$ sudo firecfg

 

Start your program the way you are used to – desktop manager menus, file manager, desktop launchers – and it will be sandboxed automatically. There are over 1000 applications supported by default in the current Firejail software version, and the number goes up with every new release.

Firefox Sandboxing Guide

The browser is by far the most important program you would ever need to protect. Take a look at Firefox Sandboxing Guide to get in the mood. Tor browser setup is discussed in All About Tor.

Firejail Usage document will help you get started in command line. If you are stuck and need help to figure something out, don’t be afraid to ask.

Do I really need to build a security profile for my application?

Building Firejail Security Profiles

No. If your application is not recognized, Firejail will use a very restrictive default profile.

Yet, we encourage users to customize profiles. Building Custom Profiles describe how to change exiting security profiles and how to create new ones.

For developers we keep a more detailed document in our wiki here, and a template in /usr/share/doc/firejail/profile.template. If you develop a profile for an application that’s not included yet in Firejail, please submit it on GitHub.

It’s too easy, I’m getting bored!

There is no difficult in Firejail, at least not SELinux-difficult. But if you need something more challenging, try to customize your security filters, or go into some more advanced security topics such as:

• Seccomp Guide
• Linux Capabilities Guide
• X11 Guide

Not quite like that, I was thinking about …

AppImage HowTo

AppImages have been cool lately. A lot of software developers are using them to distribute programs, and Firejail supports by default this technology.

There is also Stem. Take a look at this excellent article on Joris_VR blog. Both Steam and Wine games are supported by Firejail sandbox, with full sound and 3D acceleration.

 

External Reviews

If you are looking for external reviews, these are some of the best: LWN.net, DistroWatch.com, and linux.com. Linux Magazine published a very detailed feature article in April 2015. An online copy is still available here.

 

HowTo Videos

For our less-experienced Linux users, we are building a video HowTo channel. Hopefully, we can pair each video with a blog entry, if not, we provide the relevant info in the video description. Currently the videos are on Odyse.
