Using Firefox

It is possible to use Firefox instead of Chromium as follows:

1. Run sudo apt-get install firefox-esr to install Firefox ESR (you can also install a normal Firefox).
2. Edit ~/scripts/start_chromium_browser to instead call: firefox --kiosk $(/opt/custompios/scripts/get_url)
3. Optionally configure enterprise policies for browser restrictions and configuration (in case your terminal is interactive, or you want to install add-ons):
   1. sudo mkdir -p /etc/firefox/policies
   2. Create /etc/firefox/policies/policies.json using https://mozilla.github.io/policy-templates/
