If you are displeased having different anti-aliasing of fonts in your Gecko Browsers (Camino, Firefox, Flock), when WebDebug is on. Gecko Browsers will show the fonts more thiner. But when you close WebDebug, the fonts will be normal again.

I think that this is not a acceptable casualty, so i deactivate the semi-transparence of the Bar. This will correct the behavior of the Gecko engine.

Just put the code in your css file (don't modify the css of web debug):

#sfWebDebugBar, .sfWebDebugCache {
  filter:alpha(opacity=100);
  -moz-opacity:1;
  opacity: 1;
}
