- observed in WebKitGTK 2.0.1, WebKit1 API, gtk 2.24.x Steps: - add the following to any page: <script> function closeIt() { return "This page has unsaved changes."; } window.onbeforeunload = closeIt; </script> - view the page and then navigate away from it - a prompter is shown with just "This page has unsaved changes.", and OK/Cancel buttons, but indication of what they mean In previous releases the prompter had additional words like "Are you sure you want to navigate away? <page-provided message> Press OK to go, or Cancel to stay". These words are important because onbeforeunload implementers are not generally expected to provide the OK/Cancel button instructions, especially since different browsers have differently-labelled buttons in their prompters.

Actually I'm getting my renderers mixed up, it looks like WebKitGTK's onbeforeunload prompter has never had words like these (but the others do).
