Firefox MSI Installer — Enterprise Deployment Guide (2026)

Mozilla Firefox is widely used in enterprise environments, particularly where security and privacy controls are a priority. This guide covers everything IT administrators need to deploy Firefox silently via SCCM, Intune, Group Policy and PowerShell in 2026, including ADMX templates for policy management.

Download Firefox MSI Installer

Mozilla provides official MSI installers for enterprise deployment. Download directly from Mozilla’s enterprise page at mozilla.org/firefox/enterprise. Firefox ESR (Extended Support Release) is recommended for enterprise environments as it receives security updates without feature changes for approximately one year.

• Firefox MSI (Standard) — latest release, updates every 4 weeks
• Firefox ESR MSI — recommended for enterprise, longer support cycle
• Available in 64-bit and 32-bit versions
