Hm. May it be a problem of different versions? I'm using 1.7.3.
FBTrace says following:
fbs.onError (-7) with this.showStackTrace=false and
this.breakOnErrors=false kind=Uncaught-Exception
msg=document.getElementById("fbMainFrame") is null@chrome://
scraperextension/content/scraperExtension.js:387.0
Code looks like this:
initialize: function()
{
Firebug.Panel.initialize.apply(this, arguments);
Firebug.Inspector.addListener(this);
jQuery(this.panelNode, fbDocument).scroll(
function() {
if(this.scrollTop < 30)
fbDocument.getElementById("valueDiv").style.top = 5 + "px";
else
fbDocument.getElementById("valueDiv").style.top = (this.scrollTop
- 35) + "px";
FBTrace.sysout("height: " +
document.getElementById("fbMainFrame").height); //LINE 387
});
},
