After upgrading to the latest nightly build I get the following warning in the error console: reference to undefined property (this.current.Win.wrappedJSobject || this.currentWin).noscriptOverlay
and well at line 601 reading
this found to originate from noScriptservice.jsvar overlay = this.currentWin && (this.currentWin.wrappedJSObject || this.currentWin).noscriptOverlay;
What is this and what caused this, I have NoScript installed, as well as RequestPolicy, Perspectives, and PrefSwitch,
inside Minefield(Build 20090404054815)
Should this worry me?
