Just 

Reproducible: Sometimes

Steps to Reproduce:
To reproduce you have to leave FF open for some time, happens for me if I leave it open overnight.
This thread occupies 100% CPU.  It doesn't make FF unresponsive, but does make it very slow.
I'll attach 2 snapshots of the thread stacks, normal and consuming.
Attached image Normal operation
This is how the stack looks like normally.  You can see that this is the most CPU consuming threads in FF by context switch delta
CPU is 50% because machine has 2 of them...
I think this is a duplicate of Bug 365653. Please reopen if it is basically different. Maybe you could attach your screenshot there?
