Injecting Content Scripts

Welcome to Content Scripts! These are JavaScript files that run in the context of web pages loaded in the browser.

Think of them as a bridge. They allow your extension to interact with the web page's content, just like a script running directly on that page.

• Read details from a page.
• Modify the page's appearance.
• Add or remove elements.

Content scripts run in an 'isolated world'. This means they don't interfere with the page's own JavaScript environment.

Your script can access and modify the page's Document Object Model (DOM), but it can't directly access JavaScript variables or functions defined by the web page itself.

This isolation prevents conflicts and ensures your extension doesn't break the web page's functionality.
