Postman is a popular tool used by developers to test APIs quickly and efficiently. However, some users experience issues with the Postman Chrome extension not working on Windows 11. This can be frustrating, especially when you rely on it for your daily tasks.
Fortunately, there are several simple steps you can take to resolve this issue. These solutions range from basic checks to more advanced troubleshooting techniques. Follow along carefully to get your Postman extension back up and running smoothly.
In this guide, we will walk you through each step in detail so even beginners can follow without difficulty. By the end, you should have a clear understanding of how to fix the problem.
Let’s get started with some quick notes before diving into the solutions.
Quick Note: Prerequisites and Basic Checks
Before you start troubleshooting, make sure of the following:
- You have the latest version of Google Chrome installed on your Windows 11 system. Older versions may cause compatibility issues.
- Your Postman Chrome extension is installed and enabled in the browser.
- Your internet connection is stable, as Postman requires connectivity to function properly.
- Check if any firewall or antivirus software is blocking Postman or Chrome.
Verifying these points helps avoid unnecessary steps and ensures you are working with the right setup.
Step 1: Restart Chrome and Your Computer
Sometimes, the simplest solution works best. Restarting Chrome can clear temporary glitches causing the extension to malfunction.
- Close all Chrome windows completely.
- Check your Task Manager (Ctrl + Shift + Esc) to see if any Chrome processes are still running. End them if necessary.
- Restart your Windows 11 computer to refresh system resources.
- Open Chrome again and check if the Postman extension is now working.
This step ensures that any temporary bugs or stuck processes are resolved.
Step 2: Check If the Postman Extension Is Enabled
Sometimes the extension may be disabled accidentally or after an update.
- Open Google Chrome.
- Click on the three dots in the upper right corner to open the menu.
- Go to More Tools > Extensions.
- Locate the Postman extension in the list.
- Make sure the toggle switch is turned on. If it’s off, click to enable it.
- Reload your browser or the extension page to see if it works now.
Having the extension enabled is essential because a disabled extension cannot function at all.
Step 3: Clear Chrome Cache and Cookies
Old cache or corrupted cookies can interfere with how extensions operate.
- Open Chrome.
- Click the three dots menu > Settings.
- Scroll down and select Privacy and security.
- Click on Clear browsing data.
- Choose All time as the time range.
- Check Cookies and other site data and Cached images and files.
- Click Clear data.
- Restart Chrome and test the Postman extension again.
Clearing cache and cookies removes any corrupted data that might block the extension from working properly.
Step 4: Update or Reinstall the Postman Extension
An outdated or corrupted extension can cause problems. Updating or reinstalling is a reliable fix.
- Go to Chrome’s Extensions page (three dots > More Tools > Extensions).
- Enable Developer mode using the toggle at the top right.
- Click the Update button to force Chrome to check for extension updates.
- If updating doesn’t help, remove the Postman extension by clicking Remove.
- Visit the Postman Chrome Web Store page and reinstall the extension.
- Restart Chrome and test again.
Updating or reinstalling ensures you have the latest version free from bugs or corruption.
Step 5: Disable Conflicting Extensions
Other Chrome extensions may interfere with Postman’s functionality.
- Open the Extensions page in Chrome.
- Temporarily disable other extensions by toggling them off one by one.
- After disabling each extension, check if Postman works.
- If it starts working after disabling a specific extension, that extension is likely causing the conflict.
- Decide whether to keep that extension disabled or find an alternative.
Extension conflicts are common and disabling others helps isolate the issue.
Step 6: Check Chrome’s Permissions and Settings
Postman may require certain permissions to run correctly.
- Go to the Extensions page.
- Click on Details under the Postman extension.
- Ensure Allow access to file URLs is enabled if you use local files.
- Verify that the extension has necessary permissions enabled.
- Check if Chrome’s site settings or Windows firewall are blocking the extension.
Proper permissions ensure that Postman can access what it needs to function.
Step 7: Use the Standalone Postman App Instead
If the Chrome extension still does not work, consider switching to the standalone Postman desktop app.
- The standalone app is more stable and receives regular updates.
- Download it directly from the official Postman website.
- Install and run the app independently of Chrome.
- This avoids browser-related problems and often improves performance.
This alternative is recommended for users who need a reliable Postman experience on Windows 11.
FAQs
