[Bug 863133] [NEW] Firefox huge memory usage on amb64 (memory leak)

[Arthur Peters]

Public bug reported:

Behaviour I have seen:
* Start firefox
* Memory usage: ~250MB
* Use normally for 30 minutes to an hour (3-6 tabs a new page loaded every couple of minutes)
* Memory usage: ~990MB (I have seen it get as high as 1.4GB)

The memory usage does go down when I close tab and the like but overall
it only increase and the bulk of it is never freed.

I did not have this problem on Firefox 3 on 32bit (it leaked but much
slower).
