Telerik: this issue is no longer valid with latest release, planned by Mid December 2014 - we have a new Recorder UI, that does not use iFrames and will not mess up such web sites.

Hi, 

There is a custom script which throws exceptions executing over the recorder specific frames in Firefox. A major rework of the recorder is in progress though which will make this issue obsolete. Hopefully that can go live in the next few months. In the meantime  one can modify the script as a work-around, see below.

Regards!

pega.ui.ChangeTracker.prototype.trackXThreadChanges = function(portalDocument) {
var iframes = portalDocument.getElementsByTagName("IFRAME");
var len = iframes.length;
for (var i=0; i<len ; i++){
var currentIframe = iframes[i];
if(currentIframe.offsetHeight == 0 || currentIframe.contentWindow == window || !currentIframe.contentWindow.pega){
continue;
}

this.evaluateConditionsOnXThread(currentIframe.contentWindow);
}
