Some browser windows opened with JavaScript cannot be changed in size and do not show any controls. You might want to switch on some of the deactivated functions.

You can determine how your browser popups should be displayed.
For this, prevent Java Script from hiding certain control elements and functions using the extended browser configuration. Type "about:config" in the address bar of the browser and press [Enter]. In the filter field, type "dom.disable" in order to find the "dom.disable_window_open_feature. resizable" entry in the list. A double-click sets it to "true"-the size of the windows can now be changed.

At this point, you can also define many other elements that JavaScript should not hide. Set the relevant entries in extended configuration to "true" by double-clicking them. The basic elements for window management should always be visible. Theseinclude the size change option, the navigation toolbar and the "Close" button.
