Firefox with tabbed browsing (2-4tabs) on static sites without active content has memory footprint over 225K.  Starts off around 90K, but rapidly doubles/triples and then never comes back down.  CPU while generally close to idle, frequently hits 50%.  Text input, link selection, tab/menu selection frequently slow to point of nearly unusable.
