[SLUG] firefox memory

I've got an ongoing graph of Firefox's memory use. I've noticed that as
it's run over the last 5.5 days (so far), the size of its swap use has
remained about constant at around 400 MiB, but the amount of resident
(in-RAM) use has risen from around 400 MiB to around 610 MiB. Each time it
crashes it starts over. Apparently that represents a memory leak (I haven't
opened 50% more tabs), but why isn't that data swapped out? Is there a way
to allocate memory so it's never swapped out? I thought only the kernel had
that privilege so OS routines wouldn't have to deal with page faults.

What are the odds it's a plugin causing this misbehavior? I don't have that
many: Noscript, Tabsaver!, and Ubuntu Firefox Modifications. Aging Tabs,
Screengrab, and Torbutton are installed but disabled.
