'Are you sure you want to leave this page?' It's a question most of us will have been asked by our browser. Yes, we do. Don't we? Maybe we should leave it open just in case. Here we explain why some websites insist on double-checking your departure, and what you can do to stop them. Also see: Which is the best web browser for Windows?
A reader wrote into Helproom with the following question: "Sometimes when browsing the internet I come across pages which simply don’t want to go away. Instead, when I try to close the page or tab, I get a pop up saying “Are you sure you want to leave the page?” with the option to click to leave or stay on the page. I can see no reason for this behaviour other than to annoy me or trap me into staying on their site for even longer. Is there a way I can disable this feature?"
This is how we solved their problem: Although the situation you describe can be very annoying, the reasoning behind this feature is sound. Consider a site where you’re typing in a large amount of text, such as an email or filling in a long form. It could be even more annoying to inadvertently close the window with a single click and lose all of your typing. In this case, the feature gives you a chance to go back and submit or save your work before losing it, forever. For this reason, you should think carefully about disabling this feature.
