Keep every Windows endpoint converged on the same version of Mozilla Firefox with a repeatable silent deployment process built for IT operations. This guide focuses on packaging and rolling out Mozilla Firefox from its msix installer family using the verified silent install command, with admin requirements and detection rule considerations covered for dependable deployment.

Troubleshooting
If the install fails, exits with a non-zero code, or leaves no trace on the target machine, work through the checks below. Most issues come down to permissions, paths, or exit code handling.
| Run as administrator | Make sure Command Prompt or PowerShell is opened as Administrator. This installer writes to a machine-wide location and will fail silently without elevated permissions. |
|---|---|
| Verify the installer file name | Confirm that the installer file name matches the command shown in this guide: Mozilla.Firefox_151.0.4.0_x64__n80bbvh6b1yt2.msix. |
| Run from the correct folder | Run the command from the folder that contains the installer file. For batch or PowerShell deployments, place the script and installer in the same folder. |
| Check exit codes | If the installer returns a non-zero exit code, review the installer log or your deployment tool's logs. Some packages use additional success exit codes. |
| Restart if required | If the application does not appear immediately after installation, sign out and sign back in, or restart the device — this refreshes Start menu shortcuts, file associations, and Path entries written by the installer. |
| Validate detection rules | If your deployment tool reports the app as not installed, verify that the detection rule matches the installed version, MSI product code, registry key, or file path. Use the Detection Rules section above to confirm whether the application was installed successfully. |
