I am in love with Mozilla firefox as a browsing instrument but I have noticed something which I hereby see assistance on how to handle. When using other browser such Microsoft edge, chrome and internet explorer, when there's a popup window, it is scrollable but in Mozilla I found out that it is not scrollable, and as a result, I can’t preview what I want to print or decide on it. When I entered about:config on the address bar and accepted a warning message then I searched for; dom.disable_window_open_feature.scrollbars to see if I can change its value to true but unfortunately my Mozilla doesn’t have; dom.disable_window_open_feature.scrollbars What my Mozilla has are: dom.disable_window_open_feature.close;false dom.disable_window_open_feature.location;true dom.disable_window_open_feature.menubar;false dom.disable_window_open_feature.minimizable;false dom.disable_window_open_feature.personalbar;false dom.disable_window_open_feature.resizable;true dom.disable_window_open_feature.status;true dom.disable_window_open_feature.titlebar;false dom.disable_window_open_feature.toolbar;false So please, let me see if anybody know what the problem is and preferably provide me with solution
