Question about JS leaks in Firefox

[haibijon]

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?

We can't guess either. If you expand the error, it will generally show some code that caused it.

I figured as much, and that is the expanded error. It seems to be thrown by the browser itself, and there doesn't seem to be any script context. Thanks for the help though.
