Comment 15 for bug 314424

I'm seeing something very similar, but it -seems- related to how may sites I visit, as if Firefox was caching in RAM and not freeing when tab closes. If I let it, it will fill 4 GB RAM, then semi-hang while thrashing the swap file.

Also reported as launchpad bug # 126012.

This system is routinely suspended, and almost always has Firefox AND Thunderbird open. I mention Thunderbird because I'd just been watching RAM use climb for no apparent reason with just those two open, so closed Thunderbird and the RAM eating stopped, then did NOT resume when I re-opened Thunderbird.
