I've recently started checking out the leak monitor used in Jack's post a while back, and have noticed this error popping up everywhere.
Leaks in window 0x258d850:
[+] [leaked object] (27c38b0) = [Object]
[ ] _defaultLabel = Clear Private Data
Can anyone actually extract any debugging info from this? I mean, is it being caused by firefox, firebug,or my script, or is there simply no way to tell?
