Identity Safe won't fill logins.

I use Firefox v.42 browser, N360 V.22.5.4.24.  Recently, Identity Safe stopped filling logins. It won't even fill if I access a website from the saved link.  I've tried rebooting, turning off and then back on the autofill, nothing seems to work.  Any ideas? Very annoying since this is one of the features I like best about N360.  Also, no automatic prompt to login to my vault, and the Vault access is pretty well hidden. Some super update by Norton.
