Intended to be used with the GlassMyFox extension. If you have other styles that edit the border colors of toolbars they may conflict with this. Please view the code of other toolbar-altering extensions and styles before installing to ensure conflicts do not happen or are resolved.

A stupid-simple style that allows for a clear definition between the clear titlebar and the superbar/taskbar with aero. Good if you added an image to ID main-window, as there is a distinct separator line in the top and bottom which may appear more aesthetically pleasing than a sudden cut into nothing.

With some slight modification, it can also work for Thunderbird and/or other extensions. Get crazy with DOM Inspector (and optionally, recommended, InspectorWidget) to figure out the changes required to make it work as intended.

Code commented for ease of modification. Have fun!
