+An environmental variable.  Set it like this:
+ MOZ_DISABLE_IMAGE_OPTIMIZE=1 ./firefox
+It stops images from being cached on the X server on Unix/Linux.  Generally hurts performance, but gives you a more predictable pixmap usage on the server.
+===Reduce memory cache===
+ user_pref("browser.cache.memory.enable", false);
+This turns off the cache - stuart says this should be set to some minimal number otherwise you'll do a lot more decoding images over and over again.  Need to do some investigation.
