if we open window onfocus of document object then it does open window. (even with open unrequested windows unchecked") Sure it involves user action to click anywhere in document (even inside inputs) but this could be the easiest workaround since user is bound to click on document for something (mostly to fillout any information asked or to provide userID's & passwords or just to scroll or anything like that). STEPS TO REPRODUCE: 1) Uncheck preference 'Open unrequested windows'. 2) Load testcase I'm going to attach. 3) click anywhere in your content window (document). EXPECTED RESULTS: No Popup window should showup. ACTUAL RESULTS: Pop-up showsup loading yahoo.com If you try to close pop-up, it keeps on popping again (because parent document gets focus back again). This could be easy workaround. Testcase following.
