Add-ons enhance your experience on Windows 11 by adding new features or improving existing ones. However, sometimes these add-ons may stop working, causing frustration. Fortunately, fixing this issue is often straightforward.

This guide will walk you through simple and effective troubleshooting steps to get your add-ons working again. Each step is explained clearly, so even beginners can follow along without confusion.

By following these instructions, you can identify and resolve common problems causing add-ons to malfunction. Let’s start with some quick checks before moving on to detailed solutions.

Keep in mind that patience and careful attention to detail will help you fix the issue faster.

Quick Note: Prerequisites and Basic Checks

• Check Internet Connection: Some add-ons require an active internet connection to function properly.
• Verify Add-on Compatibility: Ensure the add-on is compatible with Windows 11 and the application you are using.
• Restart Your PC: Sometimes a simple restart can resolve temporary glitches affecting add-ons.
• Update Your Software: Make sure Windows 11 and the host application (like a browser or software) are fully updated.

Step 1: Enable the Add-on

Sometimes add-ons are disabled accidentally or after updates. To check if your add-on is enabled:

• Open the application where the add-on is installed (for example, Microsoft Edge or another browser).
• Go to the add-ons or extensions section. This is usually found in the settings menu.
• Look for the add-on you want to use and make sure the toggle switch is set to On or Enabled.

Why this matters: Disabled add-ons won’t work, so enabling them is the first and easiest fix.

Step 2: Update the Add-on

Outdated add-ons may stop working due to incompatibility with the latest software versions. To update your add-on:

• Open the add-ons or extensions page in your application.
• Look for an option to update add-ons or extensions manually.
• If no manual update option exists, try removing the add-on and reinstalling the latest version from the official store or website.

Why this matters: Updates fix bugs and improve compatibility, helping add-ons function correctly.

Step 3: Clear Cache and Temporary Files

Caches or temporary files can sometimes interfere with add-ons. Clearing them can help resolve conflicts.

• Open the settings in your application (browser or software).
• Find the section related to privacy or history.
• Clear cached data and temporary files.
• Restart the application and check if the add-on works.

Why this matters: Cached data may contain outdated information causing add-ons to malfunction.

Step 4: Check for Conflicting Add-ons

Sometimes multiple add-ons interfere with each other and cause problems.

• Disable all add-ons except the one you want to use.
• Restart the application.
• Check if the add-on is working.
• If it works, enable other add-ons one by one to identify the conflict.

Why this matters: Conflicts between add-ons can prevent them from functioning properly.

Step 5: Run the Application as Administrator

Some add-ons require elevated permissions to work correctly. Running the application as an administrator can help.

• Close the application.
• Right-click the application icon.
• Select Run as administrator.
• Check if the add-on works now.

Why this matters: Administrator privileges allow add-ons to access necessary system resources.

Step 6: Reinstall the Add-on

If none of the above steps work, try uninstalling and reinstalling the add-on.

• Go to the add-ons or extensions page.
• Remove or uninstall the problematic add-on.
• Restart your application.
• Download and install the latest version of the add-on from the official source.

Why this matters: Reinstallation can fix corrupted files or improper settings causing the issue.

Step 7: Check Windows Security Settings

Windows Defender or other security programs may block add-ons from working properly.

• Open Windows Security from the Start menu.
• Go to App & browser control.
• Check if any warnings or blocks are related to your add-on or application.
• Add exceptions if necessary, but only if you trust the add-on.

Why this matters: Security software might block add-ons to protect your system, but trusted add-ons should be allowed.

Step 8: Use Compatibility Mode (Advanced)

If the add-on was designed for an older version of Windows, try running the application in compatibility mode.

• Right-click the application icon.
• Select Properties.
• Go to the Compatibility tab.
• Check Run this program in compatibility mode for: and select an earlier Windows version (like Windows 10).
• Click Apply and OK.
• Restart the application and test the add-on.

Why this matters: Compatibility mode can solve issues with older add-ons not designed for Windows 11.

Frequently Asked Questions (FAQs)

When Nothing Works

If you have tried all the above steps and your add-ons still do not work, consider the following options:

• Check Official Support: Visit the official website or support forum of the add-on for specific troubleshooting guides.
• Contact Support: Reach out to the software or add-on developer for personalized help.
• Reset or Reinstall the Host Application: Sometimes reinstalling the entire application that uses the add-on can solve deep issues.

Always back up your important data before performing advanced system changes.

Fixing add-ons not working on Windows 11 is usually a matter of following simple and logical steps. Start by enabling and updating your add-ons, then clear caches and check for conflicts. If needed, run the application as administrator or reinstall the add-ons.

Understanding why each step is important helps you troubleshoot more effectively. Remember to check security settings and compatibility if problems persist. If all else fails, seek official support to resolve complex issues.
