How to use this image

Start a Firefox instance

docker run \
    --network host \
    -e DISPLAY \
    -v $HOME/.Xauthority:/home/firefox/.Xauthority:ro \
    cremuzzi/firefox

Audio support with Pulseaudio

Since tag 78.0.2-buster we switched from alsa to pulseaudio for better and simpler audio support. The container will just act as a client to your host's pulseaudio server. Just run a container with the additional volume /run/user/1000/pulse like this:

docker run \
    --network host \
    -e DISPLAY \
    -v $HOME/.Xauthority:/home/firefox/.Xauthority:ro \
    -v /run/user/1000/pulse:/run/user/1000/pulse:ro \
    cremuzzi/firefox

Hardware acceleration with mesa

Since tag firefox:68.8.0 we enabled mesa drivers for intel graphics cards, mesa-dri-intel. This solves the WebGL issue from the previous versions of this image.

To enable hardware acceleration in your dockerized firefox just share /dev/dri with your container with the --device /dev/dri run option.

Start with persistent storage

1. Create a data directory on a suitable volume on your host system, e.g. /my/own/mozilla and /my/own/downloads

2. Start your firefox container like this:

docker run \
    --network host \
    -e DISPLAY \
    -v $HOME/.Xauthority:/home/firefox/.Xauthority:ro \
    -v /run/user/1000/pulse:/run/user/1000/pulse:ro \
    -v /my/own/downloads:/home/firefox/Downloads \
    -v /my/own/mozilla:/home/firefox/.mozilla \
    cremuzzi/firefox
