​Firefox Browser, also known as Mozilla Firefox or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling ghcr.io/linuxserver/firefox should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Application Setup

The application can be accessed at:

• ​http://yourhost:3000/​

By default the user/pass is abc/abc, if you change your password or want to login manually to the GUI session for any reason use the following link:

• ​http://yourhost:3000/?login=true​

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

docker-compose (recommended, click here for more info)

---
version: "2.1"
services:
  firefox:
    image: ghcr.io/linuxserver/firefox
    container_name: firefox
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - /path/to/config:/config
    ports:
      - 3000:3000
    shm_size: "1gb"
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=firefox \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 3000:3000 \
  -v /path/to/config:/config \
  --shm-size="1gb" \
  --restart unless-stopped \
  ghcr.io/linuxserver/firefox

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (-p)

Environment Variables (-e)

Volume Mappings (-v)

Miscellaneous Options

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

​​​ ​​​

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

• Shell access whilst the container is running:

  • docker exec -it firefox /bin/bash

• To monitor the logs of the container in realtime:

  • docker logs -f firefox

• Container version number

  • docker inspect -f '{{ index .Config.Labels "build_version" }}' firefox

• Image version number

  • docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver/firefox

Versions

• 19.04.21: - Initial release.
