When Firefox downloads an update, it previously kept the update around to apply it on the next restart. This patch changes this so that the updater program is launched in the background as soon as the update has finished downloading in order to stage the updated version of the application by copying the existing installation directory to a temporary location and applying the update on top of it, and replace the existing installation directory with the staged directory on the next restart. Because the replacing step is typically very fast, this patch eliminates the wait for the update to be applied on restart, making it unnecessary to show a progress dialog when restarting. --HG-- rename : toolkit/mozapps/update/test/chrome/test_0092_finishedBackground.xul => toolkit/mozapps/update/test/chrome/test_0093_stagedBackground.xul rename : toolkit/mozapps/update/test/unit/test_0110_general.js => toolkit/mozapps/update/test/unit/test_0113_general.js rename : toolkit/mozapps/update/test/unit/test_0111_general.js => toolkit/mozapps/update/test/unit/test_0114_general.js rename : toolkit/mozapps/update/test/unit/test_0112_general.js => toolkit/mozapps/update/test/unit/test_0115_general.js rename : toolkit/mozapps/update/test/unit/test_0170_fileLocked_xp_win_complete.js => toolkit/mozapps/update/test/unit/test_0172_fileLocked_xp_win_complete.js rename : toolkit/mozapps/update/test/unit/test_0171_fileLocked_xp_win_partial.js => toolkit/mozapps/update/test/unit/test_0173_fileLocked_xp_win_partial.js rename : toolkit/mozapps/update/test/unit/test_0110_general.js => toolkit/mozapps/update/test_svc/unit/test_0113_general_svc.js rename : toolkit/mozapps/update/test/unit/test_0111_general.js => toolkit/mozapps/update/test_svc/unit/test_0114_general_svc.js rename : toolkit/mozapps/update/test/unit/test_0112_general.js => toolkit/mozapps/update/test_svc/unit/test_0115_general_svc.js rename : toolkit/mozapps/update/test/unit/test_0170_fileLocked_xp_win_complete.js => toolkit/mozapps/update/test_svc/unit/test_0172_fileLocked_xp_win_complete_svc.js rename : toolkit/mozapps/update/test/unit/test_0171_fileLocked_xp_win_partial.js => toolkit/mozapps/update/test_svc/unit/test_0173_fileLocked_xp_win_partial_svc.js
