Or maybe it just needs a kick in the pants to do garbage collection :) Try 'about:memory' and clicking on all of the buttons under 'Free memory' to see if that does anything. And try closing mail & news leaving only the browser open.

Sorry - I thought I remembered you setting it to 4GB. But in any case, bumping it up helped with the cpu busy & hangs - yes? So I'm wondering if setting the max memory entry size to -1 might help with the 'comes to a screeching halt for a couple of seconds' problem.
