I often have multiple internet windows open (often each window will have multiple tabs). I would like to be able to exit all the windows with just a single close of firefox. Currently, I can close each window that has multiple tabs with a single close. I would like to extend this to multiple windows (each with multiple tabs). In Explorer, I just right click on its icon and one of the options is to "close all windows" and that's it. I would like to see that option available on firefox. Thanks
