TheWindow.close() method closes the current window, orthe window on which it was called.

Windows arescript-closable if they were created by web content. This generally includes:

• Windows opened usingWindow.open()
• Windows opened via web content, such as links (<a>) or forms (<form>), without user modifier actions

Windows opened by browser UI actions — such as right-click → Open in new tab, Ctrl+Click, Shift+Click, or middle-click — are often not script-closable. They may only be closed if they have not been navigated (history length remains 1). Callingclose() otherwise typically shows a console warning:Scripts may not close windows that were not opened by script.

Note also thatclose() has no effect when called onWindowobjects returned byHTMLIFrameElement.contentWindow.
