So now your extension is created, let’s deploy it in chrome browser:

    1. Open chrome://extensions in chrome browser. If you are not able to open the page by clicking the URL then copy it and paste it in the address bar. Chrome could block this URL from opening for security extension page
    2. Drag your folder and drop it in this page or else you can click on Load unpacked button as highlighted in the image above. If you drop your folder in this page and the page shows the content of your folder that means you haven’t enabled Developer mode yet. So now you just have to toggle the Developer mode option in the top-right corner as highlighted in the image above.
    3. Click on the icon and enter text in the input box. Then click Alert.

      click on extension
