Firefox enterprise MSI deployment and 32-bit migration note
For enterprise Firefox deployments on Windows, prefer Mozilla’s official MSI from the enterprise channel and install it quietly with Windows Installer, for example msiexec /i FirefoxSetup.msi /qn /norestart /lv firefox-install.log. Keep the MSI architecture aligned with the deployment target so future ARP inventory and update detection stay predictable.
When migrating older 32-bit Firefox installs to 64-bit Firefox, watch for the 64-bit installer preserving the old 32-bit installation path. That can leave duplicate Add/Remove Programs entries or make later managed updates difficult to detect. For those migration rings, fully remove the old Firefox install first, including the matching uninstall registry entry and install directory, before installing the 64-bit MSI.
If your deployment wrapper uses a generic uninstall/remediation script before the 64-bit MSI, a Firefox-specific argument pattern is -DisplayName "Mozilla Firefox" -HivesToSearch HKLM -WindowsInstaller 0 -EnforcedArguments "-ms" -UninstallAll. Pilot this against mixed 32-bit/64-bit history before broad rollout so it removes stale Firefox ARP entries without touching unrelated Mozilla software.
Official Mozilla sources: Deploy Firefox with MSI installers and Firefox for Enterprise downloads.
When moving Firefox from a 32-bit install to 64-bit, the 64-bit installer can inherit the older 32-bit install location and leave duplicate Add/Remove Programs entries behind. For architecture migrations, fully remove the old Firefox install first, then deploy the target 64-bit installer silently with Firefox closed. Source: official Firefox source.
When moving Firefox from a 32-bit install to 64-bit, set and verify the intended install path instead of relying on inherited defaults. Mozilla documents silent setup with -ms and installer configuration such as InstallDirectoryPath; pinning the path helps avoid stale 32-bit registry/install-location assumptions during managed upgrades.

Firefox Enterprise MSI and ESR download-source note
Use Mozilla’s Firefox Enterprise download page for managed Firefox MSI and ESR package sourcing. It exposes enterprise-oriented Windows packages, so prefer that source over stale direct download URLs when validating current MSI/ESR media for packaging.
