Sometimes, a Chrome extension isn’t available in the Chrome Web Store, but you have the unpacked extension. In such cases, you need to install it manually. Follow the steps below to install it.
- Open Chrome Settings from the three dots in the top-right corner and select Manage Extensions, or type
chrome://extensions/in the address bar.

2. Enable Developer Mode using the toggle at the top-right of the page.

3. Click Load Unpacked and select the unzipped extension folder.

4. Navigate to the location on your system where the unpacked extension folder is located and open it.

Note: Select the folder that contains the manifest file. In the screenshot, the odoo_aliexpress_chrome_extension folder is selected because it contains the manifest.json
5. You can now see that the extension is installed in Chrome.

Sample Manifest File for extension :
{
"name": "Sample Extension",
"description": "It is used to describe manifest file",
"version": "1.0",
"manifest_version": 3,
"content_scripts": [
{
"matches": ["*://*.webkul.com/*"],
"js": ["resources/js/content.js"],
"css": ["resources/style/style.css"],
"all_frames": false
}
],
"permissions": ["activeTab"],
"icons": {
"128": "resources/image/icon.png"
},
"action": {
"default_title": "Sample application",
"default_icon": "resources/image/icon.png"
},
"web_accessible_resources": [
{
"resources": ["resources/image/*.png"],
"matches": ["<all_urls>"]
}
]
}

I am trying to use this code from labnol website ( but the problem is it shows as an app and not as an extension, I want it to show in the URL bar, other than that it does everything else)
{
“name”: “Your website name”,
“description”: “Your website description in 132 characters or less.”,
“app”: {
“urls”: [“http://www.labnol.org/”],
“launch”: {
“web_url”: “http://www.labnol.org/”
}
},
“manifest_version”: 2,
“update_url”: “http://clients2.google.com/service/update2/crx”,
“version”: “0.1”,
“icons”: {
“128”: “icon.png”
}
}
Your extension code shows in the icon but I can’t seem to figure out how to put in a website URL 😥
One way is to add popup to your extension icon and then provide information,link or button in popup.
To add popup, add below code to manifest
"browser_action": {"default_title": "title display when user hover on icon",
"default_icon": "your app icon",
"default_popup": "popup.html"
},
and add popup.html parallel to manifest file.
I check the ‘krunker skid’ extension this is not developed by
Webkulplease communicate the author for any issues.Please check your manifest file. You may refer sample manifest file updated in the blog.
Further, to check errors go to chrome://extensions/ you will get error on your extension, developer mode should be enabled.
Further, To unzip right click on the zip file and check for extract option.
