Sixteen icons, but just one button to draw 'em all
FireFox 3.0, Azerty Theme.
The text says "Show information", but I'm not sure if pressing that button will cancel, turn red?, accept, freeze?, update, turn green?, turn off and then "no"...
It's common practice to put several icons in the same image for performance reasons. Here, it seems that -moz-image-region wasn't set correctly for this button's image. Blame the theme author for this quirk (or just report it nicely).
