Further info - it looks like disabling tooltips on both firefox and the panel has resulted in fewer problems. The symptom which lead to me trying this was tiny tooltip coloured squares appearing near the panel, and really odd modal behaviour in Firefox in addition to the panel hanging. There have been previous bugs about tooltips in Firefox causing gnome-panel problems, so this might be a regression. It does not happen on my other machine which is almost identical apart from using the ATI proprietary driver. Now waiting another few days to see if things stabilise.
