Is there a way to reduce the memory usage of Firefox?

Is there a way to reduce the memory usage of Firefox? On my notebook with 2GB and Windows XP, Firefox 3.5.2 uses about 150MB of the memory with 4 tabs open. Is there a way to reduce the amount of memory that Firefox consumes?

"This works wonders!

Check your Extensions and Themes. (By running Firefox in safe mode.)
Check the Plug-ins.
Clear Download History.
Restart Firefox Periodically.
Assign Memory Cache on Firefox. (browser.cache.memory.enable and browser.cache.memory.capacity)
Release Memory when Firefox is minimized. (config.trim_on_minimize)"

In recent versions, default history setting is 90 days. This causes your Places database's size to skyrocket and can slow down Firefox considerably. Reduce your history size to something more suited to your needs.

"One of the biggest memory consumers in firefox is flash. If you can't disable the flash completely, try installing Adblock Plus. This will remove at least the flash ads (as long as the other ads)

And btw, 150MB is not that much at all."
