The biggest feature of a browser is its ability to access and display content on the World Wide Web. Browsers act as a gateway between the user and the internet, allowing users to search for and access web pages, multimedia content, and web applications.

In addition to accessing and displaying web content, browsers also provide a range of other features, including bookmarking and saving web pages, managing downloads, storing and autofilling passwords and form data, and customizing the user interface with extensions and themes. Many modern browsers also offer advanced features like tabbed browsing, private browsing modes, and synchronization across devices.
