Self-hosted Firefox

check this out… a containerized Firefox that you can self host and run in a browser!

Why? to navigate from your server wherever you are.

As the user you want to navigate with, create the docker-compose.yml file:

docker-compose.yml

version: '3'
services:
  firefox:
    image: jlesage/firefox
    ports:
      - "5800:5800"
    volumes:
      - "/user/appdata/firefox:/config:rw"

adapt your port (5800) and config path (/user/appdata/firefox).

Now, setup a tunnel from your local PC to the server:

ssh external-server1 -L5800:127.0.0.1:5800

and then fireup your browser to http://127.0.0.1 and navigate with firefox-in-the-browser! (this tunnel step is not needed if you setup the reverse proxy as indicated below)

Create the following NGINX config:

firefox.conf

location /firefox/ {
        rewrite ^/firefox/(.*) /$1 break;
        proxy_ignore_client_abort on;
        proxy_pass   http://127.0.0.1:5800;
        proxy_redirect  http://127.0.0.1:5800 /firefox;
        proxy_cookie_path / /firefox/;
    }

See The Reverse Proxy concept for more info.

You might also want to start your container at boot in the usual way adding it to /etc/local.d/80-containers.start & stop.
