# Firefox in Docker

## Launching the Firefox

```
alias firefox="docker-compose -f ~/docker/firefox/docker-compose.yml run --rm firefox"
```

# Troubleshooting

```

## 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
