When I was running Firefox 1.5 on my work machine, I was also monitoring
memory use. It was very noticeable that the memory pressure on the (2Gb)
machine gradually grew until it hit swap. Killing and restarting all
firefoxes helped.
Upgrading to Firefox 2 made a huge difference for me. FF 2.0 still leaks
memory, but it does so an order of magnitude slower than FF 1.5 did, and
is more stable as well. The peak memory use of Firefox 2 also seems to
be more constrained than 1.5 was. You should really upgrade - it's worth
it. Just be wary of extensions that don't play nice (WeatherFox, for one).
