Bubblejail is a bubblewrap-based alternative to Firejail.
Bubblejail's design is based on observations of Firejail's faults.
One of the biggest issues with Firejail is that you can accidentally run unsandboxed applications and not notice.
Bubblejail, instead of trying to transparently overlay an existing home directory, creates a separate home directory.
Every Instance represents a separate home directory. Typically, every sandboxed application has its own home directory.
Each instance has a services.toml file which defines the configuration of the instance such as system resources that the sandbox should have access to.
Service represents some system resources that the sandbox can be given access to. For example, the Pulse Audio service gives access to the Pulse Audio socket so that the application can use sound.
Profile is a predefined set of services that a particular application uses. Using profiles is entirely optional.
If your distro does not have a package you can try to manually install with meson
- Python 3 (>= 3.9) - python interpreter
- Jinja2 - Python template engine used during build
- Meson - build system
- scdoc - man page generator (optional)
- Python 3 (>= 3.9) - python interpreter
- Python PyXDG - XDG standards for python
- Python Tomli - TOML file support for python,
tomliversion - Python Tomli-W - writer part of
tomli - Bubblewrap (>= 0.5.0) - sandboxing command line utility
- XDG D-Bus Proxy - filtering dbus proxy
- Python Qt6 - for GUI
- libseccomp - helper library for seccomp rules
- Desktop File Utils - allows new desktop entries to be registered
- notify-send - command to send desktop notification (part of
libnotify)
- bash-completion - auto-completions for bash shell
- fish - auto-completions for fish shell
- slirp4netns - for alternative networking stack
- Run
meson setup buildto setup build directory - Switch to build directory
cd build - Compile
meson compile - Install
sudo meson install
If you want to uninstall run ninja uninstall from build directory.
Configuration utility
- Install bubblejail from AUR git or AUR stable
- Install the application you want to sandbox (for example, firefox)
- Run GUI. (should be found under name
Bubblejail Configuration) - Press 'Create instance' button at the bottom.
- Select a profile. (for example, firefox)
- Optionally change name
- Press 'Create'
- The new instance is created along with new desktop entry.
bubblejail create --profile firefox FirefoxInstance
bubblejail run FirefoxInstance
bubblejail create --no-desktop-entry --profile generic Test
