Enable beforeunload checking


If you enable this setting, IE Tab will check the current page for beforeunload or onbeforeunload event handlers before unloading the page.

If you disable this setting, IE Tab will not invoke beforeunload before unloading the page. For legacy reasons this setting is disabled by default.
