A browser extension is a small software program that adds new features or enhances the functionality of a web browser such as Chrome, Firefox, or Edge. These extensions are installed directly into the browser and integrate seamlessly to improve the user’s browsing experience.Browser extensions are typically developed using web technologies like HTML, CSS, and JavaScript. They can interact with web pages, modify content, block ads, manage or provide tools like grammar checking, screen capturing, and productivity enhancements.
Extensions run within the browser environment and often use APIs provided by the browser to tabs, storage, and other features while maintaining security and user privacy.Overall, browser extensions are lightweight yet powerful tools that customize and extend browser capabilities, making everyday online tasks more efficient and convenient.
