XPCSafeJSObjectWrapper.cpp Problem Rated 5 out of 5 stars
In the "Error Console" I am constantly getting this warning:
reference to undefined property this [arguments] #
Where the "#" symbol is, just replace it with a number that keeps on rising, I guess that means that this warning/error keeps on looping. All this goes away as soon as your extension is disabled and afterwords Firefox has been restarted. I am using Firefox 3 RC1.
