Prerequisites

To follow along with this tutorial, you'll need:* A computer with a modern web browser
* A text editor or IDE
* Basic knowledge of HTML, CSS, and JavaScript

Getting Started

To create a new web extension project, open your text editor or IDE and create a new file. Save the file with a .js extension, such as .

In the file, add the following code:```
const extension = {
manifest: {
name: "My Extension",
version: "1.0",
description: "A simple web extension that adds a button to the toolbar.",
permissions: ["tabs"]
},
background: {
scripts: [""]
},
browser_action: {
default_title: "My Extension",
default_icon: "",
onClick: function() {
({url: ""});
}
}
};
(() => {
(extension.browser_action);
});
```

This code defines the manifest for your extension. The manifest contains information about your extension, such as its name, version, description, and permissions. It also defines the background script and browser action for your extension.

To package your extension, open your terminal and run the following command:```
web-ext build --target zip
```

This will create a .zip file containing your packaged extension.

To publish your extension, visit the Chrome Web Store and click the "Publish" button. You'll need to provide a name, description, and icon for your extension, as well as a link to your packaged extension.

Conclusion

Congratulations! You've now created, packaged, and published your first web extension. In this tutorial, you learned the basics of web extension development. You can now use this knowledge to create your own extensions to customize your web browsing experience.
