Yep, you can adjust the max amount of cache it will store in ram and disk(separately).

  I don't see any option to separate that in the settings page, is it hidden behind a flag somewhere?

    In about:config search for browser.cache.memory.capacity and browser.cache.disk.capacity.They are in kilobytes. To enable or disable any of those caches use browser.cache.disk.enable and browser.cache.memory.enable.
