Norton Security did not start after updates yesterday

After updates yesterday, on starting the pc this morning I realised Norton Security had not started. I only knew because I opened Chrome to make use of my Vault, could not get Norton Toolbar. It took a couple of full reboots before NS was running and Toolbar/Vault.

What totally bothers me is there was no notification/warning and I normally use Firefox.

This seems to be caused by the updates? Never had this before. What is going on? Also issue of no Vault for Firefox is relevant, if i'd just used FF as usual I have been unprotected for....
