It doesn't really matter how much memory I have (4G) , my point is that
the memory usage was a factor of *10* higher than it should have been,
and that the bloat happened while I wasn't even interacting with it.
Adding more memory to deal with a process that just eats all available
memory (which is what appears to be happening; my large swap partition
was fully in use before I kill FF) doesn't solve anything.

With the 3.x series I used to leave a firefox session up for a month at
a time.  Now it appears I have to restart it every day.  I'm
uncomfortable with the slide towards Window-95-style "oh, just reboot
every day"...
