Deploy Firefox ESR 102 (Latvian) (x64) with Intune

Overview

Follow these Intune deployment steps for Firefox ESR 102 (Latvian) (x64) 102.15.1 from Mozilla to keep packaging, assignment, and troubleshooting consistent.

Download Installer

Prepare the Intune Package

1. Create a working folder on your local machine (for example: D:\Intune).
2. Create two subfolders inside the working folder: Input and Output.
   • D:\Intune\Input: Folder for all setup files. All files in this folder are compressed into an .intunewin file.
   • D:\Intune\Output: Stores the generated .intunewin package.
3. Place Firefox Setup 102.15.1esr.exe in the Input folder.
4. Download the Microsoft Win32 Content Prep Tool (IntuneWinAppUtil.exe) and place it in D:\Intune.

Start by organizing a dedicated packaging folder for Firefox ESR 102 (Latvian) (x64) to keep input binaries and generated .intunewin files traceable.

D:\Intune
├── Input
│   └── Firefox Setup 102.15.1esr.exe
├── Output
└── IntuneWinAppUtil.exe

5. Open Windows PowerShell or Command Prompt as Administrator.
6. Navigate to the working folder: cd D:\Intune.
7. Run the following packaging command to generate the Firefox Setup 102.15.1esr.intunewin package. For packaging background, see .intunewin package preparation.

IntuneWinAppUtil.exe -c .\Input -s "Firefox Setup 102.15.1esr.exe" -o .\Output

8. After the command finishes, the generated package should be available in the D:\Intune\Output folder.

D:\Intune
├── Input
│   └── Firefox Setup 102.15.1esr.exe
├── Output
│   └── Firefox Setup 102.15.1esr.intunewin
└── IntuneWinAppUtil.exe

Note: Windows application size is capped at 30 GB per app.

Scope Assignment and Deployment

14. Scope assignments for Firefox ESR 102 (Latvian) (x64) by rollout intent and ring maturity instead of moving directly to full production.

    Assignment options

    Required

    Installs the app automatically on targeted users or devices. Use this after install, uninstall, and detection are verified.

    Available for enrolled devices

    Shows the app in Company Portal so users can install it manually. Use this for pilot users, IT validation, or optional apps.

    Uninstall

    Automatically removes the app from targeted devices. Use this when you need to retire or remove the app.

    Note: Start with a dedicated test group before broad deployment. For example, use the Required assignment option to automatically install the app on targeted devices.

    

15. Review all configuration details, then click Create to deploy the app.

    

16. Verify the app in Intune. Confirm that the upload is finished, the application is saved, and the app overview shows the expected package details.

    Note: If Intune says the app is not ready yet, wait a few minutes and refresh the page.

    

Sync the Intune Policies

Trigger and confirm policy sync for Firefox ESR 102 (Latvian) (x64) before troubleshooting deeper packaging assumptions.

End User Experience

Confirm expected end-user experience for Firefox ESR 102 (Latvian) (x64) on pilot endpoints before broad rollout communications.

Required apps install automatically. During installation, Windows may show notifications from Microsoft Intune Management Extension. Users can see the app move from installing to installed.

Note: Notification visibility depends on Windows notification settings and Intune app deployment behavior.

Monitor Deployment Status

Review deployment status for Firefox ESR 102 (Latvian) (x64) with return-code context so escalation is evidence-driven.

Click Device install status or User install status to see the list of devices or users with their installation status.

Uninstall the App from Intune

When the app is no longer needed, remove it by changing the Intune assignment to Uninstall for the target group.

1. Go to Apps → All apps, then select the app you want to remove.

   

2. Open Properties and click Edit next to Assignments.

   

3. Move the target group to the Uninstall section.

   

4. Review the assignment, then click Save. Devices will remove the app after the policy is applied.

   

After saving, the uninstall policy is applied. The device removes the app automatically.

Note: The uninstall process may take a few minutes depending on device check-in and policy sync timing.

Common Issues and Resolutions

Start with these troubleshooting checks to identify whether the issue is assignment, execution context, detection configuration, or policy sync timing.

Deployment Fit and Risks

Before production rollout, verify that Firefox ESR 102 (Latvian) (x64) matches your target context, change policy, and monitoring posture.

• Install behavior is currently set to system; confirm it matches the expected execution context.
• Restart behavior resolves to basedOnReturnCode; align this with maintenance windows and user-impact constraints.
• Validate requirements and detection against real endpoint state before widening assignment scope.
• Escalate only after reproducing failures in pilot scope with logs and consistent return-code evidence.

Validation Steps Before Broad Rollout

• Use a phased rollout for Firefox ESR 102 (Latvian) (x64), beginning with a small validation cohort.
• Confirm the install command executes silently in the target context: "Firefox Setup 102.15.1esr.exe" /S /DesktopShortcut=false /StartMenuShortcut=false /MaintenanceService=false /PreventRebootRequired=false.
• Validate detection outputs (types observed: manual/unspecified) using post-install file and registry checks.
• Capture deployment status, error codes, and retry behavior in Intune reports before expanding assignment.
• Ensure rollback notes align with tested uninstall behavior before broad deployment.

Change and Rollback Notes

• Record pilot baseline details for Firefox ESR 102 (Latvian) (x64) (version 102.15.1) prior to wider deployment.
• Rollback path available via uninstall command: "%ProgramFiles%\Mozilla Firefoxuninstallhelper.exe" -ms.
• Treat rollback as a tested path, not a plan-only artifact, before moving beyond pilot cohorts.
• If this package supersedes another app, complete coexistence checks before removing legacy assignments.
