Norton identity safe not saving logins in Firefox 52.0.2

I have windows 10 laptop, but I only use  Firefox, after firefox updated to 52.0.2  identity safe does not save logins on new sites, and although I have logins in the id list if I go on the site ID safe says "0 login"  and some of my sites will not autofill, My Norton is updated to the latest, I am really fed up with this, I may not renew Norton when it runs out, I am in the UK by the way.
