Browser functionality refers to the features and tools that web browsers, like Google Chrome or Mozilla Firefox, provide to help users access and navigate the internet. Key functions include displaying web pages, managing bookmarks, and allowing users to open multiple tabs for easy multitasking. Browsers also support various extensions and plugins that enhance user experience by adding extra features. Another important aspect of browser functionality is security. Modern browsers come with built-in protections against malware and phishing attacks, ensuring safer browsing. They also offer privacy settings, such as incognito mode, which allows users to browse without saving their history. Overall, these functionalities make web browsing efficient and secure.
