A browser extension is a small software module that adds functionality to a web browser. Extensions can enhance the browser's capabilities, offering new features, modifying the appearance of websites, or improving user experience. They are typically written in web technologies like HTML, CSS, and JavaScript, and can be installed directly from a browser's extension store or marketplace.
Key Features of Browser Extensions:
Extend Browser Functionality: Browser extensions can add new features to the browser, such as ad-blocking, password management, or language translation tools.
Integration with Web Pages: Extensions interact with the content of websites that users visit. For example, they can change the layout of a page, highlight text, or add shortcuts to websites.
Access to Browser APIs: Extensions can use APIs provided by the browser to interact with its features, such as managing tabs, sending notifications, or accessing bookmarks.
User Customization: Many extensions offer customization options, allowing users to personalize their browsing experience by changing themes, adding toolbars, or altering specific website behaviors.
