Sebastian, The currentVersion pref is indeed set to 1.9.0 here. I have also tried undoing the change I made to showFirstRunPage and the behavior seems correct - it isn't loading every time I start Firefox anymore.
Sorry if I have caused confusion with what is obviously an intermittent and local issue, but I do appreciate the help.
