I can help you write code for a Microsoft Edge browser extension, leveraging the information from the web search results. Microsoft Edge extensions are built using web technologies like HTML, CSS, and JavaScript, and they follow the same structure as Chrome extensions since Edge is Chromium-based. Below, I’ll create a simple Microsoft Edge extension that displays a pop-up with a random quote when the user clicks the extension icon. I’ll walk through the necessary files, code, and steps to get it running, based on the tutorial structure in (docs.microsoft.com) and the general guidance in (learn.microsoft.com).
Microsoft Edge Extension: Random Quote Generator
This extension will:
- Display a pop-up with a random quote when the user clicks the extension icon.
- Use a simple HTML/CSS interface for the pop-up.
- Include a JavaScript file to fetch and display a random quote.
- Be compatible with Microsoft Edge, as it’s Chromium-based.
Step 1: Set Up the Directory Structure
Create a folder for your extension (e.g., random-quote-extension) with the following files:
- manifest.json (defines the extension’s metadata and permissions)
- popup.html (the pop-up UI)
- popup.css (styles for the pop-up)
- popup.js (logic to display a random quote)
- icon.png (a 128×128 icon for the extension)
Step 2: Create the manifest.json File
The manifest.json file is the core configuration file for the extension. It defines the extension’s name, version, permissions, and the pop-up file to display.
{
“manifest_version”: 3,
“name”: “Random Quote Generator”,
“version”: “1.0”,
“description”: “Displays a random quote in a pop-up.”,
“action”: {
“default_popup”: “popup.html”,
“default_icon”: “icon.png”
},
“permissions”: [],
“icons”: {
“128”: “icon.png”
}
}
- manifest_version: 3 is the latest version as of 2025, ensuring compatibility with modern Edge requirements.
- action specifies the pop-up file (popup.html) to display when the icon is clicked.
- No permissions are needed since this extension doesn’t access external APIs or user data.
Step 3: Create the popup.html File
This file defines the structure of the pop-up window.
<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset=”UTF-8″>
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
<title>Random Quote</title>
<link rel=”stylesheet” href=”popup.css”>
</head>
<body>
<div class=”container”>
<h1>Random Quote</h1>
<p id=”quote”>Click the button to get a quote!</p>
<button id=”getQuoteBtn”>New Quote</button>
</div>
<script src=”popup.js”></script>
</body>
</html>
- The pop-up includes a heading, a paragraph to display the quote, and a button to fetch a new quote.
- It links to popup.css for styling and popup.js for functionality.
Step 4: Create the popup.css File
This file styles the pop-up to make it visually appealing.
body {
width: 300px;
font-family: Arial, sans-serif;
margin: 0;
padding: 10px;
background-color: #f0f0f0;
}.container {
text-align: center;
}h1 {
font-size: 18px;
color: #333;
margin-bottom: 10px;
}p#quote {
font-style: italic;
color: #555;
margin: 10px 0;
min-height: 40px;
}button {
background-color: #0078d4;
color: white;
border: none;
padding: 8px 16px;
cursor: pointer;
border-radius: 4px;
font-size: 14px;
}button:hover {
background-color: #005ea2;
}
- The styles ensure the pop-up is compact (300px wide, as typical for browser pop-ups) and user-friendly, with a clean design.
Step 5: Create the popup.js File
This file contains the JavaScript logic to display a random quote when the button is clicked.
document.addEventListener(‘DOMContentLoaded’, function() {
const quoteElement = document.getElementById(‘quote’);
const getQuoteBtn = document.getElementById(‘getQuoteBtn’);// Array of sample quotes
const quotes = [
“The only way to do great work is to love what you do. – Steve Jobs”,
“Life is what happens when you’re busy making other plans. – John Lennon”,
“In the middle of difficulty lies opportunity. – Albert Einstein”,
“You miss 100% of the shots you don’t take. – Wayne Gretzky”,
“The best way to predict the future is to create it. – Peter Drucker”
];// Function to get a random quote
function displayRandomQuote() {
const randomIndex = Math.floor(Math.random() * quotes.length);
quoteElement.textContent = quotes[randomIndex];
}// Display a quote on button click
getQuoteBtn.addEventListener(‘click’, displayRandomQuote);// Display a quote when the pop-up loads
displayRandomQuote();
});
- The script waits for the DOM to load, then sets up a button event listener to display a random quote from an array.
- A quote is also displayed immediately when the pop-up opens, enhancing user experience.
Step 6: Add an Icon
You’ll need a 128×128 PNG image named icon.png for the extension’s icon. You can create a simple image (e.g., a quote bubble) using any graphic design tool, or download a free icon from a site like Flaticon (ensure proper licensing). Place it in the extension folder.
Step 7: Load and Test the Extension in Microsoft Edge
- Open Microsoft Edge.
- Go to edge://extensions/.
- Enable “Developer mode” (toggle in the top-right corner).
- Click “Load unpacked” and select your random-quote-extension folder.
- The extension should appear in your toolbar. Click its icon to see the pop-up, and test the “New Quote” button.
Step 8: Publish the Extension (Optional)
If you want to publish this extension, you can submit it to the Microsoft Edge Add-ons website. You’ll need to:
- Register a developer account with a Microsoft account.
- Package your extension files into a ZIP file.
- Submit it via the Edge Add-ons developer dashboard.
Conclusion
This simple Microsoft Edge extension demonstrates the basics of creating a pop-up, which builds an extension to display an image in a pop-up without JavaScript. Our version adds interactivity with JavaScript, showing how to enhance functionality while keeping the code minimal. The extension is fully compatible with Microsoft Edge since it’s Chromium-based, and it can be easily modified to include more features, like fetching quotes from an API (which would require adding permissions in the manifest). This code provides a solid starting point for anyone looking to develop their own Edge extension.
