This situation becomes very irritating with time. The user might be writing a post, a comment or filling an online form. Since Google Chrome, Microsoft Edge and Opera browsers do not show any confirmation message before closing the window, if a user accidentally clicks on close button or presses keyboard shortcuts to close the browser window, he’ll lose all running tabs and all the data typed in online forms. In this way, he’ll not lose his tabs and any data entered into text boxes, form fields, etc. Since the user clicked on the close button accidentally, he may click on the Cancel button present in the notification message dialog box to keep the browser window open. It asks for the user confirmation before closing multiple tabs. It shows a confirmation prompt asking for the permission from the user to exit from the browser window.

In such situations, the “Warn on Close” feature comes to the rescue. Sometimes a user is working on multiple tabs and he might accidentally click on the close (x) button of the window or might press hotkeys such as Alt+F4, Ctrl+Shift+Q (has been disabled in Chrome 70 and later), etc which are used to close browser window. “Warn on Close” feature prevents the web browser from accidentally closing multiple running tabs. Google Chrome, Microsoft Edge and Opera browsers are based on Chromium browsing engine so all have similar features and functionality. “ Warn on Close” (also known as warn on exit or warn on quit) is an essential feature which should be present in all web browsers but unfortunately some popular web browsers such as Google Chrome, Microsoft Edge and Opera lack this basic functionality.
