Chrome is the most popular web browser today, with over 60% of the market share. It is known for its simplicity, speed, and security, making it the ideal browser for everyday use. However, one of the best things about Chrome is the ability to add extensions to enhance your browsing experience. This article will guide you through the process of creating a Chrome extension that works for you.

What is a Chrome Extension?

A Chrome extension is a small software program that extends the functionality of the Chrome browser. It can add new features to the browser, modify existing features, or change the appearance of the browser. Chrome extensions can be found in the Chrome Web Store, and they are easy to install and use.

Why Build Your Own Chrome Extension?

There are many reasons why you may want to build your own Chrome extension. For example, you may want to automate a task that you perform regularly, add a feature that you can't find in other extensions, or simply customize your browsing experience to better suit your needs. Whatever your reason, building a Chrome extension is a relatively simple process that anyone can do.

What You Need to Know Before You Start

Before you start building your Chrome extension, you need to have a basic understanding of HTML, CSS, and JavaScript. You should also have a general understanding of how web pages work. If you are not familiar with these technologies, it may be a good idea to take a course or read a book to familiarize yourself with them.


Before you start building your Chrome Extension, you'll need to have a few things in place:

  1. A Google Chrome browser installed on your computer
  2. Basic knowledge of HTML, CSS, and JavaScript
  3. A text editor such as Visual Studio Code

Setting up the Development Environment

To set up your development environment, follow these steps:

  1. Open Google Chrome and go to the Chrome Web Store
  2. Click on the "Developers Dashboard" button
  3. Sign in with your Google account
  4. Click on the "Add new item" button
  5. Fill out the required information, such as the extension name, description, and version number

Step 1: Decide What You Want Your Extension to Do

The first step in building a Chrome extension is to decide what you want your extension to do. This could be anything from adding a new feature to your browser to changing the appearance of your browser. Once you have a clear idea of what you want your extension to do, you can move on to the next step.

Step 2: Create a Manifest File

A manifest file (manifest.json) is a simple JSON file that tells Chrome about your extension. It includes information such as the name of your extension, the version number, and the permissions that your extension needs. The manifest file is the first thing that Chrome will look for when you load your extension, so it is important to get it right.

Here’s the Basic Format.

"manifest_version": 2,
"description": "DESCRIPTION",
"version": "1.0",
"browser_action": {
"default_icon": “ICON (WITH EXTENSION) ”,
"default_popup": “LAYOUT HTML FILE"
"permissions": [

Here is our Manifest.json file

    "name": "Random HEX Color Generator",
    "version": "1.0.0",
    "description": "Random HEX Color Generator",
    "manifest_version": 3,
    "author": "codewithFaraz",
        "default_popup": "data.html",
        "default_title": "Random HEX Color Generator"

Step 3: Write Your Code

Once you have your manifest file in place, it's time to start writing your code. Your code should be written in HTML, CSS, and JavaScript, and it should be designed to do what you want your extension to do. There are many resources available online to help you get started with writing your code, including tutorials, forums, and blogs.

Create a new file called data.html.

It is the HTML that POPS UP when you click the Chrome extension button.

<!DOCTYPE html>
    <title>Random HEX Color Generator</title>
    <meta charset="utf-8">
	<link rel="stylesheet" href="styles.css">
  <h1 id="colour">#e63c44</h1>
  <button id="change">New Colour</button>
  <script src="scrip.js"></script>
Create the JavaScript file, let’s call it, scrip.js, Since we are creating a simple HTML file, you can skip this step completely as our present project won’t be needing any JavaScript.
var btn = document.getElementById('change');
var text = document.getElementById('colour');

var generator = function() {
  newColour = '#'+(Math.random()*0xFFFFFF<<0).toString(16);
  if(newColour.length < 7) {

btn.addEventListener('click', function() {
    generator(); = newColour; = newColour;
    text.innerText = newColour;

Step 4: Test Your Extension

Once you have written your code, it's time to test your extension. You can do this by loading your extension into the Chrome browser. You can load your extension by navigating to the extensions page or Opening the chrome://extensions page, clicking on the "Developer Mode" button, and then clicking on the "Load Unpacked" button upload your folder.

Step 5: Publish Your Extension
