I stumbled upon Firefox 3 Memory Usage via Twitter tonight.  The post, from Mozilla software engineer Pavlov, goes into great detail about many of the various memory usage-related changes and fixes that have gone into Firefox 3.  Those changes include, but are not limited to, reduced memory fragmentation, cache tuning, image data storage improvements and memory leak reduction.  Be sure to read the full post if you’re interested in those gory details.
