Firebug Won't Even Show Me Where This Is

[dog-tag]

There is certain tabs which I can't find even when using firebug.



See the black tabs? I have spent HOURS on top of HOURS searching for these tabs.
I have found the color of the text, but I can't get those tab backgrounds anywhere.

Any time I hover over them to select them they turn grey. Firebug won't give me a clear path either, does anyone know what these tabs are?

They're being used by vbexperience and vbarcade only. Advice is much appreciated.

Found it now, by searching the elements, then go through all the variables.
The variable that controls it is called - Block Sub-Header Background

That's been annoying me for 3 months now!
