731105 - npr.org zombie compartment

Status: RESOLVED INCOMPLETE

(Core :: General, defect)

Description

[Brian Carpenter [:geeknik]]

It's been about 6 hours since I visited this URL on npr.org and closed the associated tab, but the compartment is still alive and well.

I opened about:ccdump, clicked Run CC Analysis to get the current object graph, searched for nsDocument to see a zombie document object and got this:

And after clicking on Show Graph for the zombie document:

about:compartments?verbose shows:

Hopefully this information is helpful.

Does this occur with safe mode or all add-ons disabled?

Doesn't happen in safe mode. But why this URL and not the 500 or so other URLs I've looked at since then?

> Doesn't happen in safe mode.

That suggests it's an add-on that's causing it.  Firefox 15 was released yesterday and it fixes most add-on zombie compartment leaks.  In the absence of other info, I'm closing this.  If you can still reproduce on Firefox 15, please reopen and tell us which add-ons you have installed (by cutting and pasting the contents of about:support).  Thanks!
