Closing an open tab refers to the action of terminating a specific webpage or document that is currently being displayed in a web browser. Each tab within a browser represents an independent browsing session, allowing users to navigate and access multiple websites simultaneously.
Closing open tabs can enhance the overall browsing experience and improve the performance of your device. It helps to conserve system resources, reduce memory usage, and prevent potential browser slowdowns. Additionally, closing unnecessary tabs can help declutter the browsing interface, making it easier to locate and switch between active tabs.
