I’ve been trying to register my extension, but it keeps failing. I’m not sure if I’m missing a step or installing it incorrectly. Could you please provide clear instructions or guide me through the proper installation and registration process? This issue is urgent as I need the extension to be up and running.

    Dear @Rz L ,

    Thank you for reaching out regarding the issue you're facing with registering your Microsoft Edge extension. We understand how important it is to get your extension up and running promptly, and we’re here to assist you.

    Based on your query, it seems you’re encountering difficulties with the registration process, possibly related to loading or submitting your extension. To help resolve this, we recommend following the steps outlined in our official documentation for registering as a Microsoft Edge extension developer and submitting an extension.

    Steps to Register and Load Your Extension

    1. Create a Microsoft Account (MSA):
      • If you don’t already have an MSA (e.g., an Outlook.com, Live.com, or Hotmail.com account), create one at account.microsoft.com or use your GitHub account to sign into Partner Center, which will automatically create an MSA for you.
    2. Enroll in the Microsoft Edge Program:
      • Visit Partner Center and sign in with your MSA.
      • Complete the registration form, selecting either an individual or company account, and provide the required details (e.g., publisher display name, contact information).
      • Accept the Microsoft Store App Developer Agreement and submit the form.
    3. Load an Unpacked Extension for Testing:
      • If you’re testing locally, open Microsoft Edge and navigate to edge://extensions/.
      • Enable "Developer mode" and select "Load unpacked."
      • Choose the folder containing your extension’s manifest.json file.
      • If you encounter errors, check the console for details via Edge DevTools or by inspecting the extension.
    4. Troubleshooting Tips:
      • Manifest Errors: Ensure your manifest.json is valid (e.g., correct syntax, required fields like manifest_version: 3, name, and version).
      • File Path Issues: Select the root folder of your extension, not a subfolder.
      • Permissions: Run Edge as an administrator if you face access issues.
      • Browser Version: Update to the latest Edge version via edge://settings/help.

    If you’re attempting to publish your extension to the Microsoft Edge Add-ons store, ensure your Partner Center account is verified. For company accounts, verification may take a few days to weeks, as outlined in the documentation.

    In the meantime, please review the linked documentation for a step-by-step guide: Register as a Microsoft Edge extension developer.
