I don't think you're crazy.  I have had the same problem for a long
time.  I have been going on the assumption that a tab is just another
instance of a window, but someone mentioned that tabs are to blame.
Apparently the coding for tabs manages memory differently than
windows.  I haven't done an experiment to open up numerous windows to
see if that causes the same problem.  Has anyone done this???

Here are the details fo my memory problems.  I'm using Seamonkey ver.
2.0.4.  As I open and close tabs, or basically just use my browser the
available memory gradually decreases until it's down to 10% or less.
At this point my system becomes so slow that I have to do something
about it.  I've watched the memory as I close each window full of
tabs.  (I use SpeedItUpFree memory manager to watch the memory.)  Each
closed window adds a little to the available memory until it reaches
25% or so.  Upon closing the last window the memory shoots all the way
up to 70% or 80%, so it looks like it's the core Seamonkey module that
is to blame, not individual windows or tabs.

I also have used the memory management feature of SpeedItUpFree and
recovered some memory, but it doesn't work as well as simply closing
Seamonkey down now and running it again.  There are, of course, times
when Seamonkey 2 freaks out and then I reboot my system.  It's an
imperfect situation, but I'm glad there is a relatively simple way to
get things running smoothly again until the next meltdown.

My subjective impression -- based on no actual measurements -- is that SeaMonkey runs fine until it fills up its cache, then it slows down quite a bit until I clear the cache. It doesn't seem to be very efficient at pushing the oldest data out of the cache to make room for newer data.

For this reason, I set a large cache size (512 MB at the moment, half my physical memory).

YMMV
