Run Firefox in unprivileged podman container

• With audio (assuming host uses pulse)
• With video
• root account not involved

Why

• Improve host system isolation from potentially harmful code running in the browser
• Make tracking of your internet presence a little bit harder

Run

IMPORANT - close firefox if it's already running.

If you have podman:

make build
make run

If you prefer docker:

make build DOCKER=docker
make run DOCKER=docker

Hardening

Firefox will, by default, run with hardened user.js preferences. If you prefer raw firefox settings then run like this:

make run_no_hardening

Troubleshooting

• If you are using podman and fall into weird issues while running this container please check if your /etc/containers/seccomp.json diverted from https://github.com/raw/containers/common/main/pkg/seccomp/seccomp.json To check if seccomp.json might be an issue add --security-opt seccomp=unconfined to podman run options. It is also possible to use downloaded seccomp.json by adding following to podman run options: --security-opt seccomp=/path/to/the/seccomp.json
