I saw Jörg Sommer's thread on firefox-dev recently and tried to repeat the steps, but got different results:

It seems strange to me that there are three windows open to Google Maps, when I don't have any tabs open to it at the moment. I'm guessing these are being kept around due to an add-on or something? I currently have installed:

(I just disabled About Sync and Activity Stream since I don't use them, but they could still be related.) Does anything seem suspicious here?

Ethan, it looks like you have a leaky add-on (and a ton of ghost windows). Can you try reproducing in safe mode? If you don't see the leaks then you can try re-enabling add-ons selectively.

Never mind, in the intervening month I have switched to using Nightly on this computer and I no longer have Firefox open long enough to encounter this kind of issue. Thanks for the help.
