I am creating them free, all I ask is that you thank me/+ Rep me.
Here are examples:

Just tell me what colors, top and bottom, and give me the image to use (already rendered please) to put in the Userbar, say you want a firefox userbar with the icon, you send me the rendered Icon, I give you a userbar. Or you can use the smiley I have, or the FF Icon I have. Enjoy,
Form:

What color: Top, Bottom
What image, and download:
Want the diagonal lines:
Want it bordered:
Want the shine:


You must provide the image rendered, or pick the smiley I have! Or I cannot create you a userbar! Sorry for any inconvenience.
