The technology that allows users to easily switch between different tabs in a web browser is called a tabbed interface. This feature provides a convenient way to organize and access multiple web pages within a single browser window. Users can open multiple tabs and switch between them without losing their place, improving the overall browsing experience by reducing clutter and enhancing navigation. Additionally, tabbed browsing enables easier access to frequently visited sites and facilitates multitasking by allowing users to compare content across different tabs seamlessly.
