Firefox in Docker

Launching the Firefox

You can use the following shortcut function and place it to your ~/.bash_aliases file

alias docker="sudo -E docker"
alias docker-compose="sudo -E docker-compose"

function docker_helper() { { pushd ~/docker/$1; docker-compose rm -fa "$1"; docker-compose run -d --name "$1" "$@"; popd; } }
function firefox() { { docker_helper $FUNCNAME $@; } }

Troubleshooting

Audio

Following are some useful commands which you can use for testing the audio

docker-compose run --rm --entrypoint /bin/bash firefox
apt-get update && apt-get install -y alsa-utils
aplay -L
pactl list
cat /dev/urandom | aplay -
arecord -D pulse -f cd | aplay -D pulse -B 10000 -

Video

Go to about:support in the Firefox to see whether everything is OK or not.

Codecs and the HW acceleration

You may want to disable Google's VP8 & VP9 video codecs: "MSE & WebM VP9" and "WebM VP8" as there is no hardware decoding for them. To do this, install h264ify extension from

https://addons.mozilla.org/en-us/firefox/addon/h264ify/

Check the codecs
