Resize Popups in Firefox

You might have come upon some popups that did not display all information because their dimension was to small to do so. Unfortunately though the developer has configured the popup this way that resizing is not working. This often happens when the developer created the popup for another browser, Internet Explorer for instance, and did not test it in Firefox or Opera.

There is however a way in Firefox to override the “cannot resize popup” setting which in turn makes it possible to resize any popup that you might come across. To do so you need to type about:config in the address bar of Firefox and filter for the term dom.disable_window_open_feature.resizable.

Set the value of this setting to true to be able to resize all windows in Firefox. The easiest way to do that is to simply double-click the entry. You can right-click the entry and select Toggle from the menu alternatively.
