If you use Firefox, especially in a tiling window manager where 'popup' isn't really a meaningful feature, you may find it annoying that websites will open windows that have functionality disabled. Go to about:config, accept the warning, and search for 'dom.disable_window_open_feature'. This will give a list of controls that websites may want to remove in windows they open. Setting any item to 'true' will disable the website's ability to screw with it. #firefox #countWebula
