Popular browsers like Google Chrome, Mozilla Firefox, and Microsoft Edge offer features such as tabbed browsing, bookmarks, and extensions for customization. They employ rendering engines to interpret HTML, CSS, and JavaScript code to render web pages accurately. Security features like sandboxing and private browsing protect users' privacy and data. Browsers also support various web standards and protocols, ensuring compatibility with different websites. Their continual development aims to enhance speed, security, and functionality for users worldwide.
