## Requirements

- [Docker Engine](https://docs.docker.com/engine/) (Docker Desktop is not required!)
- [x11docker](https://github.com/mviereck/x11docker)

## Build browser image

    $ docker build -t firefox .

## X server image

To use the `--xc` option, we need either to pull the out-dated image,

    $ docker pull x11docker/xserver

or, to build a newer image locally (preferred).

    $ x11docker --build x11docker/xserver

## Run

    $ ./x11docker -I --xc --share $HOME/Downloads -- --tmpfs /dev/shm -- firefox
