i was able to reproduce this 2 times out of 5 tries. It seems it depend on the time when i close the Firefox Window.

Jonas, is this maybe just another example for a shutdown leak, or could this be a different leak?

[Jonas Sicking (:sicking) No longer reading bugmail consistently]

This only leaks if you shut down at the "wrong" time. So it's not going to accumulate over time and so won't affect users.

However it seems like something that could show up often in testing so keeping blocking but giving lower priority.
