Enterprise Policies

Introduction

Enterprise policies control Firefox behavior and let you centrally manage various aspects of Firefox across devices. Policies can be applied using Group Policy, Microsoft Intune, or by creating a file called policies.json and defining policies within the JSON.

The reference documentation for each policy, including guides for applying and managing them, is in the Firefox Admin Documentation. For other resources for deploying Firefox in an organization, see the Firefox Enterprise page.

Kiosk Mode

Firefox Kiosk Mode is a basic full-screen mode intended for environments where the content displayed in the browser is controlled by a kiosk owner. It’s designed for cases where users have no keyboard access or where keyboard access is restricted (particularly Ctrl and Alt). Kiosk administrators are responsible for ensuring that content displayed on the device cannot unexpectedly navigate users away.

To run Kiosk Mode, start Firefox from the command line with the --kiosk option:

firefox --kiosk
# Or provide a URL
firefox --kiosk 'https://example.com/my-dashboard'

To put the kiosk window on a particular monitor, use --kiosk-monitor with the monitor number, instead:

# --kiosk-monitor implies --kiosk
firefox --kiosk-monitor 1 'https://example.com/my-dashboard'

Kiosk Mode does three main things:

  1. Main browser windows (not popup windows) switch to full-screen mode that can’t be exited within Firefox.

  2. The context menu isn’t shown.

  3. Status for URLs and page loading isn’t shown.

Two policies that are important for for a kiosk are UserMessaging and DisableFirefoxStudies. Together they stop Firefox from interrupting the kiosk content with recommendations, onboarding, What’s New, and studies.

Kiosk mode also won’t suppress updates, the notifications and restart prompts for them, block about: pages, developer tools, and other behavior, so you should use policies for controlling these, too.
