The author has marked this style as obsoleted by Fx3: FamFamFam iconic menu.
Doesn't work in Fx3 and too complex. You can still use this style if you still use Fx2, don't update in this case. I recommend to use other my styles or parental styles of my styles.
// Compilation of "Iconic Menubar - FamFamFam" and "Icons-Only Menubar" styles.
This style _replace_ text menus in Fx, Tb, Sb and some extensions with cool icons from FamFamFam iconset.
p.s. "Chipmarks" block marked as comment because in original FamFamFam icons style there is no encoded image. If it's correctly work w/o commenting -- tell me please.
UPD: Added padding for general menu elements. Now style normally work on Vista.
menubar > menu > * { padding: 1px !important; }
If you want, you can change it to 2px, in some cases it's better.
